| * mci: stm32_sdmmc2: move command timeout errors to debug levelLucas Stach2020-05-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | Command timeouts are sometimes a normal operating condition (for example when probing whether the connected card is SD or MMC), so we don't want to print an error message for all of them. Move those messages to the debug level, the MCI core will print some more meaningful messages on most command errors anyways.

| * stm32mp: init: fix up st, package into stm32mp pinctrl nodesAhmad Fatoum2020-05-121-15/+48
| | | | | | | | | | | | | | | | | | | | | | Since Linux v5.1, the pinctrl driver can use the st,package property if provided to validate whether the ball to be configured exists on the package. The upstream device trees provide this property, but if we'll want barebox to supply it instead, so we can use the same barebox binary for different SoC variants.

| | | | | | | | | | | | | | | | | | | | Setting the NVMEM stride to 4 means we can't have nvmem cells pointing at odd addresses. Linux sets it to 1 instead and handles reads at unaligned addresses by splitting them up to aligned chunks. Copy over the code to do the same. Unaligned writes remain illegal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revision A was 0x1000 and B was 0x2000, so I assumed the next would be revision C valued 0x3000. Alas, it's revision Z with 0x2001... Change the code accordingly and add detection for the new 800Mhz profiles.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The enet_out clock gate is wrongly abstracted. The bit it is controlling is not just a bit to enable the clock, it also controls the direction of the ethernet reference clock. When the bit is cleared, the ethernet reference clock must be fed into the SoC from an external oscillator; when it's set then the ethernet reference clock is generated internally. The correct setting depends on the board, so we must not set the bit unconditionally during probe of the clock driver. Whether or not the clock is enabled can be selected by the board by removing the clock from the FEC in its dts. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The device tree is based on the one in linux-stm32/stm32-next, which will probably be merged for Linux v5.8-rc1. Instead of waiting that long, we import it here with some stuff removed/changed, so it's usable for both barebox and Linux, without the prerequisite patches. The non-barebox specific parts have been moved into separate DTSIs (arch/arm/dts/stm32mp{157c-lxa-mc1,15xx-osd32}.dtsi), so both can be dropped after the v5.8-rc1 sync with only include path change necessary in arch/arm/dts/stm32mp157c-lxa-mc1.dts.

Port over the at91bootstrap driver to barebox. Some parts are based on the U-Boot and Linux implementations. To support future use in PBL, the driver model and driver implementation parts are split into separate files with the latter being compilable for PBL as well. Registers, which are found in the common Linux sdhci.h have been added to the barebox sdhci.h. Registers which appear to be Atmel specific have been added to atmel-sdhci-common.c instead. The driver still misses some parts, which will follow later: - ADMA is unsupported, PIO only for now - Only the SD/MMC controller already enabled by the first stage bootloader is supported. Further clocking changes appear to be necessary to enable another Both can be retrofitted later on and don't hold us back from booting from MMC.
