|\ | | | | | | | | | | | | | | | | | | | | i2c changes for 2020.04 - updates the Designware I2C driver - get timings from device tree - handle units in nanoseconds - make sure that the requested bus speed is not exceeded - few smaller clean-ups - adds enums for i2c speed and update drivers which use them - global_data: remove unused mxc_i2c specific field

| * i2c: designware_i2c: Separate out the speed calculationSimon Glass2020-01-272-33/+48
| | | | | | | | | | | | | | | | | | | | | | We want to be able to calculate the speed separately from actually setting the speed, so we can generate the required ACPI tables. Split out the calculation into its own function. Drop the double underscore on __dw_i2c_set_bus_speed while we are here. That is reserved for compiler internals.

| * i2c: designware_i2c: Rewrite timing calculationSimon Glass2020-01-271-22/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the driver can end up with timing parameters which are slightly faster than those expected. It is possible to optimise the parameters to get the best possible result. Create a new function to handle the timing calculation. This uses a table of defaults for each speed mode rather than writing it in code. The function works by calculating the 'period' of each bit on the bus in terms of the input clock to the controller (IC_CLK). It makes sure that the constraints are met and that the different components of that period add up correctly. This code was taken from coreboot which has ended up with this same driver, but now in a much-different form. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the driver uses an approximation for the bus clock, e.g. 166MHz instead of 166 2/3 MHz. This can result in small errors in the resulting I2C speed, perhaps 0.5% or so. Adjust the existing code to start from the accurate figure, even if later rounding reduces this accuracy. Update the bus speed code to work in KHz instead of MHz, which removes most of the error. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>

It assumes all read operations to be in Quad mode and thus does not support SFDP parsing. Also, adding support for new mode such as Octal mode would not be possible with current configuration. Therefore move the driver over to spi-mem framework. This has added advantage that driver can be used to support SPI NAND memories too. Hence, move driver over to new spi-mem APIs. Please note that this gets rid of mode bit setting done when CONFIG_SPL_SPI_XIP is defined as there does not seem to be any user to that config option.

However the hitherto code allowed to accidentally override those settings in the spi_get_bus_and_cs() routine. The initially established speed could be discarded by using the slave platdata, which turned out to be an issue on the platforms whose slave maximum supported frequency is not on par with the maximum frequency of the bus controller. This patch fixes above issue by configuring the bus from spi_get_bus_and_cs() only in case it was not done before.

It uses the new spi-mem interface and does not expose the more generic spi-xfer interface. The source was taken from the v5.3-rc3 tag. The port was straightforward: - remove the interrupt handling and the completion by busy polling the controller - remove locks - move the setup of the memory windows into claim_bus() - move the setup of the speed into set_speed() - port the device tree bindings from the original fspi_probe() to ofdata_to_platdata() There were only some style change fixes, no change in any logic. For example, there are busy loops where the return code is not handled correctly, eg. only prints a warning with WARN_ON(). This port intentionally left most functions unchanged to ease future bugfixes. This was tested on a custom LS1028A board. Because the LS1028A doesn't have proper clock framework support, changing the clock speed was not tested. This also means that it is not possible to change the SPI speed on LS1028A for now (neither is it possible in the linux driver).
