* net: fec_mxc: Add board_interface_eth_init() for i.MX8M Mini/Nano/PlusMarek Vasut2023-03-301-0/+4
| | | | | | | | | | Implement common board_interface_eth_init() and call it from the FEC driver to configure IOMUXC GPR[1] register according to the PHY mode obtained from DT. This supports all three interface modes supported by the i.MX8M Mini/Nano/Plus FEC and supersedes the current board-side configuration of the same IOMUX GPR[1] duplicated in the board files.

* net: fec_mxc: Add ref clock setup support for i.MX8M Mini/Nano/PlusMarek Vasut2023-03-301-0/+32
| | | | | | | | | The FEC ref clock frequency on i.MX8M Mini/Nano/Plus was so far configured via ad-hoc board code. Replace that with DM clock clk_set_rate() instead. This way, the driver claims all its required clock and sets the ref clock rate, without any need of architecture specific register fiddling. Signed-off-by: Marek Vasut <marex@denx.de>

* net: fec: add support for DM_MDIOTim Harvey2023-02-021-2/+88
| | | | | | | | | | | | | | Add support for DM_MDIO by registering a UCLASS_MDIO driver and attempting to use it. This is necessary if wanting to use a DSA driver for example hanging off of the FEC MAC. Care is taken to fallback to non DM_MDIO mii bus as several boards define DM_MDIO without having the proper device-tree configuration necessary such as an mdio subnode, a phy-mode prop, and either a valid phy-handle prop or fixed-phy subnode which will cause dm_eth_phy_connect() to fail.

* global: Finish CONFIG -> CFG migrationTom Rini2023-01-201-4/+4
| | | | | | | | | | | | | At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

* net: fec: prevent undesired de-assertion of phy-reset on requestTim Harvey2022-04-101-1/+1
| | | | | | | | | | | | | | | | | When gpio_request_by_name allocates a gpio output it by default will de-assert the gpio which for phy-reset will take the PHY out of reset. As this occurs before fec_gpio_reset is called to assert the reset line it can cause undesired affects if reset timings are not properly met. Configure the gpio with GPIOD_IS_OUT_ACTIVE so that reset is kept active (reset asserted) to avoid this.

* net: fec: use device sequence vs index when fetching fecTim Harvey2021-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | When using uclass_get_device* to get the FEC device we need to use device sequence instead of index into UCLASS_ETH. In systems where for example a I2C based DSA switch exists it will probe before the FEC master and its ports will be registered first and have the first indexes yet the FEC's sequence comes from the device-tree alias. Take for example the imx8mm-venice-gw7901 board which has an i2c based DSA switch: u-boot=> net list eth1 : lan1 00:0d:8d:aa:00:2f eth2 : lan2 00:0d:8d:aa:00:30 eth3 : lan3 00:0d:8d:aa:00:31 eth4 : lan4 00:0d:8d:aa:00:32 eth0 : ethernet@30be0000 00:0d:8d:aa:00:2e active Thus in this case uclass_get_device(UCLASS_ETH, 0, &dev) returns lan1 which is wrong but uclass_get_device_seq(UCLASS_ETH, 0, &dev) returns ethernet@30be000 which is correct.

But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit.

* net: fec: Allow the PHY node to be retrievedFabio Estevam2020-06-221-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we move towards driver model, it is required to let the FEC driver know how to properly deal with an Ethernet PHY subnode in the device tree. For example: &fec { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_microsom_enet_ar8035>; phy-handle = <&phy>; phy-mode = "rgmii-id"; phy-reset-duration = <2>; phy-reset-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>; status = "okay"; mdio { #address-cells = <1>; #size-cells = <0>; phy: ethernet-phy@0 { reg = <0>; qca,clk-out-frequency = <125000000>; }; }; }; Currently the PHY node pointer is incorrectly associated with the Ethernel controller instead of the PHY node itself. This causes the PHY properties, such as "qca,clk-out-frequency" in the example above to not get parsed. Fix this problem by populating the phy_of_node node.

| | | | | | | | | | | | | | | | | | | | At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL.
