With driver model, 'struct spi_slave' still +exists, but now it is 'per-child data' for the SPI bus. Each child of the +SPI bus is a SPI slave. The information that was stored in the +driver-specific slave structure can now be port in private data for the +SPI bus. + +For example, struct tegra_spi_slave looks like this: + +.. code-block:: c + + struct tegra_spi_slave { + struct spi_slave slave; + struct tegra_spi_ctrl *ctrl; + }; + +In this case 'slave' will be in per-child data, and 'ctrl' will be in the +SPI's buses private data. + + +How long does this take? +------------------------ + +You should be able to complete this within 2 hours, including testing but +excluding preparing the patches.

Since all the methods return an error initially, there is +less chance that you will accidentally leave something in. + +Also, even though your conversion is basically a rewrite, it might help +reviewers if you leave functions in the same place in the file, +particularly for large drivers. + + +Add some includes +----------------- + +Add these includes to your driver: + +.. code-block:: c + + #include <dm.h> + #include <errno.h> + + +Build +----- + +At this point you should be able to build U-Boot for your board with the +empty SPI driver. You still have empty methods in your driver, but we will +write these one by one. + +Set up your platform data structure +----------------------------------- + +This will hold the information your driver to operate, like its hardware +address or maximum frequency. + +You may already have a struct like this, or you may need to create one +from some of the #defines or global variables in the driver. + +Note that this information is not the run-time information. It should not +include state that changes. It should be fixed throughout the live of +U-Boot. Run-time information comes later. + +Here is what was in the exynos spi driver: + +.. code-block:: c + + struct spi_bus { + enum periph_id periph_id; + s32 frequency; /* Default clock frequency, -1 for none */ + struct exynos_spi *regs; + int inited; /* 1 if this bus is ready for use */ + int node; + uint deactivate_delay_us; /* Delay to wait after deactivate */ + }; + +Of these, inited is handled by DM and node is the device tree node, which +DM tells you. The name is not quite right. So in this case we would use: + +.. code-block:: c + + struct exynos_spi_platdata { + enum periph_id periph_id; + s32 frequency; /* Default clock frequency, -1 for none */ + struct exynos_spi *regs; + uint deactivate_delay_us; /* Delay to wait after deactivate */ + }; + + +Write ofdata_to_platdata() [for device tree only] +------------------------------------------------- + +This method will convert information in the device tree node into a C +structure in your driver (called platform data). If you are not using +device tree, go to 8b. + +DM will automatically allocate the struct for us when we are using device +tree, but we need to tell it the size: + +.. code-block:: c + + U_BOOT_DRIVER(spi_exynos) = { + ... + .platdata_auto_alloc_size = sizeof(struct exynos_spi_platdata), + + +Here is a sample function. It gets a pointer to the platform data and +fills in the fields from device tree. + +.. code-block:: c + + static int exynos_spi_ofdata_to_platdata(struct udevice *bus) + { + struct exynos_spi_platdata *plat = bus->platdata; + const void *blob = gd->fdt_blob; + int node = dev_of_offset(bus); + + plat->regs = (struct exynos_spi *)fdtdec_get_addr(blob, node, "reg"); + plat->periph_id = pinmux_decode_periph_id(blob, node); + + if (plat->periph_id == PERIPH_ID_NONE) { + debug("%s: Invalid peripheral ID %d\n", __func__, + plat->periph_id); + return -FDT_ERR_NOTFOUND; + } + + /* Use 500KHz as a suitable default */ + plat->frequency = fdtdec_get_int(blob, node, "spi-max-frequency", + 500000); + plat->deactivate_delay_us = fdtdec_get_int(blob, node, + "spi-deactivate-delay", 0); + debug("%s: regs=%p, periph_id=%d, max-frequency=%d, deactivate_delay=%d\n", + __func__, plat->regs, plat->periph_id, plat->frequency, + plat->deactivate_delay_us); + + return 0; + } + + +Add the platform data [non-device-tree only] +-------------------------------------------- + +Specify this data in a U_BOOT_DEVICE() declaration in your board file: + +.. code-block:: c + + struct exynos_spi_platdata platdata_spi0 = { + .periph_id = ... + .frequency = ... + .regs = ... + .deactivate_delay_us = ... + }; + + U_BOOT_DEVICE(board_spi0) = { + .name = "exynos_spi", + .platdata = &platdata_spi0, + }; + +You will unfortunately need to put the struct definition into a header file +in this case so that your board file can use it. + + +Add the device private data +--------------------------- + +Most devices have some private data which they use to keep track of things +while active. This is the run-time information and needs to be stored in +a structure. There is probably a structure in the driver that includes a +'struct spi_slave', so you can use that. + +.. code-block:: c + + struct exynos_spi_slave { + struct spi_slave slave; + struct exynos_spi *regs; + unsigned int freq; /* Default frequency */ + unsigned int mode; + enum periph_id periph_id; /* Peripheral ID for this device */ + unsigned int fifo_size; + int skip_preamble; + struct spi_bus *bus; /* Pointer to our SPI bus info */ + ulong last_transaction_us; /* Time of last transaction end */ + }; + + +We should rename this to make its purpose more obvious, and get rid of +the slave structure, so we have: + +.. code-block:: c + + struct exynos_spi_priv { + struct exynos_spi *regs; + unsigned int freq; /* Default frequency */ + unsigned int mode; + enum periph_id periph_id; /* Peripheral ID for this device */ + unsigned int fifo_size; + int skip_preamble; + ulong last_transaction_us; /* Time of last transaction end */ + }; + + +DM can auto-allocate this also: + +.. code-block:: c + + U_BOOT_DRIVER(spi_exynos) = { + ... + .priv_auto_alloc_size = sizeof(struct exynos_spi_priv), + + +Note that this is created before the probe method is called, and destroyed +after the remove method is called. It will be zeroed when the probe +method is called. + + +Add the probe() and remove() methods +------------------------------------ + +Note: It's a good idea to build repeatedly as you are working, to avoid a +huge amount of work getting things compiling at the end. + +The probe method is supposed to set up the hardware. U-Boot used to use +spi_setup_slave() to do this. So take a look at this function and see +what you can copy out to set things up. + +.. code-block:: c + + static int exynos_spi_probe(struct udevice *bus) + { + struct exynos_spi_platdata *plat = dev_get_platdata(bus); + struct exynos_spi_priv *priv = dev_get_priv(bus); + + priv->regs = plat->regs; + if (plat->periph_id == PERIPH_ID_SPI1 || + plat->periph_id == PERIPH_ID_SPI2) + priv->fifo_size = 64; + else + priv->fifo_size = 256; + + priv->skip_preamble = 0; + priv->last_transaction_us = timer_get_us(); + priv->freq = plat->frequency; + priv->periph_id = plat->periph_id; + + return 0; + } + +This implementation doesn't actually touch the hardware, which is somewhat +unusual for a driver. In this case we will do that when the device is +claimed by something that wants to use the SPI bus. + +For remove we could shut down the clocks, but in this case there is +nothing to do. DM frees any memory that it allocated, so we can just +remove exynos_spi_remove() and its reference in U_BOOT_DRIVER. + + +Implement set_speed() +--------------------- + +This should set up clocks so that the SPI bus is running at the right +speed. With the old API spi_claim_bus() would normally do this and several +of the following functions, so let's look at that function: + +.. code-block:: c + + int spi_claim_bus(struct spi_slave *slave) + { + struct exynos_spi_slave *spi_slave = to_exynos_spi(slave); + struct exynos_spi *regs = spi_slave->regs; + u32 reg = 0; + int ret; + + ret = set_spi_clk(spi_slave->periph_id, + spi_slave->freq); + if (ret < 0) { + debug("%s: Failed to setup spi clock\n", __func__); + return ret; + } + + exynos_pinmux_config(spi_slave->periph_id, PINMUX_FLAG_NONE); + + spi_flush_fifo(slave); + + reg = readl(®s->ch_cfg); + reg &= ~(SPI_CH_CPHA_B | SPI_CH_CPOL_L); + + if (spi_slave->mode & SPI_CPHA) + reg |= SPI_CH_CPHA_B; + + if (spi_slave->mode & SPI_CPOL) + reg |= SPI_CH_CPOL_L; + + writel(reg, ®s->ch_cfg); + writel(SPI_FB_DELAY_180, ®s->fb_clk); + + return 0; + } + + +It sets up the speed, mode, pinmux, feedback delay and clears the FIFOs. +With DM these will happen in separate methods. + + +Here is an example for the speed part: + +.. code-block:: c + + static int exynos_spi_set_speed(struct udevice *bus, uint speed) + { + struct exynos_spi_platdata *plat = bus->platdata; + struct exynos_spi_priv *priv = dev_get_priv(bus); + int ret; + + if (speed > plat->frequency) + speed = plat->frequency; + ret = set_spi_clk(priv->periph_id, speed); + if (ret) + return ret; + priv->freq = speed; + debug("%s: regs=%p, speed=%d\n", __func__, priv->regs, priv->freq); + + return 0; + } + + +Implement set_mode() +-------------------- + +This should adjust the SPI mode (polarity, etc.). Again this code probably +comes from the old spi_claim_bus(). Here is an example: + +.. code-block:: c + + static int exynos_spi_set_mode(struct udevice *bus, uint mode) + { + struct exynos_spi_priv *priv = dev_get_priv(bus); + uint32_t reg; + + reg = readl(&priv->regs->ch_cfg); + reg &= ~(SPI_CH_CPHA_B | SPI_CH_CPOL_L); + + if (mode & SPI_CPHA) + reg |= SPI_CH_CPHA_B; + + if (mode & SPI_CPOL) + reg |= SPI_CH_CPOL_L; + + writel(reg, &priv->regs->ch_cfg); + priv->mode = mode; + debug("%s: regs=%p, mode=%d\n", __func__, priv->regs, priv->mode); + + return 0; + } + + +Implement claim_bus() +--------------------- + +This is where a client wants to make use of the bus, so claims it first. +At this point we need to make sure everything is set up ready for data +transfer. Note that this function is wholly internal to the driver - at +present the SPI uclass never calls it. + +Here again we look at the old claim function and see some code that is +needed. It is anything unrelated to speed and mode: + +.. code-block:: c + + static int exynos_spi_claim_bus(struct udevice *bus) + { + struct exynos_spi_priv *priv = dev_get_priv(bus); + + exynos_pinmux_config(priv->periph_id, PINMUX_FLAG_NONE); + spi_flush_fifo(priv->regs); + + writel(SPI_FB_DELAY_180, &priv->regs->fb_clk); + + return 0; + } + +The spi_flush_fifo() function is in the removed part of the code, so we +need to expose it again (perhaps with an #endif before it and '#if 0' +after it). It only needs access to priv->regs which is why we have +passed that in: + +.. code-block:: c + + /** + * Flush spi tx, rx fifos and reset the SPI controller + * + * @param regs Pointer to SPI registers + */ + static void spi_flush_fifo(struct exynos_spi *regs) + { + clrsetbits_le32(®s->ch_cfg, SPI_CH_HS_EN, SPI_CH_RST); + clrbits_le32(®s->ch_cfg, SPI_CH_RST); + setbits_le32(®s->ch_cfg, SPI_TX_CH_ON | SPI_RX_CH_ON); + } + + +Implement release_bus() +----------------------- + +This releases the bus - in our example the old code in spi_release_bus() +is a call to spi_flush_fifo, so we add: + +.. code-block:: c + + static int exynos_spi_release_bus(struct udevice *bus) + { + struct exynos_spi_priv *priv = dev_get_priv(bus); + + spi_flush_fifo(priv->regs); + + return 0; + } + + +Implement xfer() +---------------- + +This is the final method that we need to create, and it is where all the +work happens. The method parameters are the same as the old spi_xfer() with +the addition of a 'struct udevice' so conversion is pretty easy. Start +by copying the contents of spi_xfer() to your new xfer() method and proceed +from there. + +If (flags & SPI_XFER_BEGIN) is non-zero then xfer() normally calls an +activate function, something like this: + +.. code-block:: c + + void spi_cs_activate(struct spi_slave *slave) + { + struct exynos_spi_slave *spi_slave = to_exynos_spi(slave); + + /* If it's too soon to do another transaction, wait */ + if (spi_slave->bus->deactivate_delay_us && + spi_slave->last_transaction_us) { + ulong delay_us; /* The delay completed so far */ + delay_us = timer_get_us() - spi_slave->last_transaction_us; + if (delay_us < spi_slave->bus->deactivate_delay_us) + udelay(spi_slave->bus->deactivate_delay_us - delay_us); + } + + clrbits_le32(&spi_slave->regs->cs_reg, SPI_SLAVE_SIG_INACT); + debug("Activate CS, bus %d\n", spi_slave->slave.bus); + spi_slave->skip_preamble = spi_slave->mode & SPI_PREAMBLE; + } + +The new version looks like this: + +.. code-block:: c + + static void spi_cs_activate(struct udevice *dev) + { + struct udevice *bus = dev->parent; + struct exynos_spi_platdata *pdata = dev_get_platdata(bus); + struct exynos_spi_priv *priv = dev_get_priv(bus); + + /* If it's too soon to do another transaction, wait */ + if (pdata->deactivate_delay_us && + priv->last_transaction_us) { + ulong delay_us; /* The delay completed so far */ + delay_us = timer_get_us() - priv->last_transaction_us; + if (delay_us < pdata->deactivate_delay_us) + udelay(pdata->deactivate_delay_us - delay_us); + } + + clrbits_le32(&priv->regs->cs_reg, SPI_SLAVE_SIG_INACT); + debug("Activate CS, bus '%s'\n", bus->name); + priv->skip_preamble = priv->mode & SPI_PREAMBLE; + } + +All we have really done here is change the pointers and print the device name +instead of the bus number. Other local static functions can be treated in +the same way. + + +Set up the per-child data and child pre-probe function +------------------------------------------------------ + +To minimise the pain and complexity of the SPI subsystem while the driver +model change-over is in place, struct spi_slave is used to reference a +SPI bus slave, even though that slave is actually a struct udevice. In fact +struct spi_slave is the device's child data. We need to make sure this space +is available. It is possible to allocate more space that struct spi_slave +needs, but this is the minimum. + +.. code-block:: c + + U_BOOT_DRIVER(exynos_spi) = { + ... + .per_child_auto_alloc_size = sizeof(struct spi_slave), + } + + +Optional: Set up cs_info() if you want it +----------------------------------------- + +Sometimes it is useful to know whether a SPI chip select is valid, but this +is not obvious from outside the driver. In this case you can provide a +method for cs_info() to deal with this. If you don't provide it, then the +device tree will be used to determine what chip selects are valid. + +Return -ENODEV if the supplied chip select is invalid, or 0 if it is valid. +If you don't provide the cs_info() method, -ENODEV is assumed for all +chip selects that do not appear in the device tree. + + +Test it +------- + +Now that you have the code written and it compiles, try testing it using +the 'sf test' command. You may need to enable CONFIG_CMD_SF_TEST for your +board. + + +Prepare patches and send them to the mailing lists +-------------------------------------------------- + +You can use 'tools/patman/patman' to prepare, check and send patches for +your work. See the README for details. + +A little note about SPI uclass features +--------------------------------------- + +The SPI uclass keeps some information about each device 'dev' on the bus: + + struct dm_spi_slave_platdata: + This is device_get_parent_platdata(dev). + This is where the chip select number is stored, along with + the default bus speed and mode. It is automatically read + from the device tree in spi_child_post_bind(). It must not + be changed at run-time after being set up because platform + data is supposed to be immutable at run-time. + struct spi_slave: + This is device_get_parentdata(dev). + Already mentioned above. It holds run-time information about + the device. + +There are also some SPI uclass methods that get called behind the scenes: + + spi_post_bind(): + Called when a new bus is bound. + This scans the device tree for devices on the bus, and binds + each one. This in turn causes spi_child_post_bind() to be + called for each, which reads the device tree information + into the parent (per-child) platform data. + spi_child_post_bind(): + Called when a new child is bound. + As mentioned above this reads the device tree information + into the per-child platform data + spi_child_pre_probe(): + Called before a new child is probed. + This sets up the mode and speed in struct spi_slave by + copying it from the parent's platform data for this child. + It also sets the 'dev' pointer, needed to permit passing + 'struct spi_slave' around the place without needing a + separate 'struct udevice' pointer. + +The above housekeeping makes it easier to write your SPI driver. diff --git a/doc/driver-model/spi-howto.txt b/doc/driver-model/spi-howto.txt deleted file mode 100644 index 38c26f642b..0000000000 --- a/doc/driver-model/spi-howto.txt +++ /dev/null @@ -1,623 +0,0 @@ -How to port a SPI driver to driver model -======================================== - -Here is a rough step-by-step guide.

A little note about SPI uclass features: - -The SPI uclass keeps some information about each device 'dev' on the bus: - - struct dm_spi_slave_platdata - this is device_get_parent_platdata(dev) - This is where the chip select number is stored, along with - the default bus speed and mode. It is automatically read - from the device tree in spi_child_post_bind(). It must not - be changed at run-time after being set up because platform - data is supposed to be immutable at run-time. - struct spi_slave - this is device_get_parentdata(dev) - Already mentioned above. It holds run-time information about - the device. - -There are also some SPI uclass methods that get called behind the scenes: - - spi_post_bind() - called when a new bus is bound - This scans the device tree for devices on the bus, and binds - each one. This in turn causes spi_child_post_bind() to be - called for each, which reads the device tree information - into the parent (per-child) platform data. - spi_child_post_bind() - called when a new child is bound - As mentioned above this reads the device tree information - into the per-child platform data - spi_child_pre_probe() - called before a new child is probed - This sets up the mode and speed in struct spi_slave by - copying it from the parent's platform data for this child. - It also sets the 'dev' pointer, needed to permit passing - 'struct spi_slave' around the place without needing a - separate 'struct udevice' pointer. - -The above housekeeping makes it easier to write your SPI driver. diff --git a/doc/driver-model/usb-info.txt b/doc/driver-model/usb-info.rst index e07e5ba261..1817df420f 100644 --- a/doc/driver-model/usb-info.txt +++ b/doc/driver-model/usb-info.rst @@ -1,3 +1,5 @@ +..

At present there is no option + to add a flat binary with a load/start address, similar to the + 'add-flat-binary' option in cbfstool. + + cbfs-offset: + This is the offset of the file's data within the CBFS.
