2022-02-09mmc: fsl_esdhc_imx: fix watermark level in dmaMarcel Ziswiler1-3/+2
Seems that we need the waterlevel setting not only for PIO mode as without this at least the i.MX 8M Mini won't boot anymore when being written by such a U-Boot. Corruption has also been observed both on the i.MX 6 as well as i.MX 8M Mini when using ums on the eMMC. Fix this by setting the watermark level again regardless of whether in DMA or PIO mode.

2021-11-30mmc: stm32_sdmmc2: Add support for probing bus voltage level translatorMarek Vasut1-1/+62
Add support for testing whether bus voltage level translator is present and operational. This is useful on systems where the bus voltage level translator is optional, as the translator can be auto-detected by the driver and the feedback clock functionality can be disabled if it is not present. The translator test sets CMD high to avoid interfering with a card, and then verifies whether signal set on CK is detected on CKIN. If the signal is detected, translator is present, otherwise the CKIN feedback clock are disabled.

With the recent changes on mmc driver, we saw that the boot is ~5 secs longer compared to v2021.07 on mediatek platforms. This regression is seen during mmc_init and caused by the following patch [1]. Indeed since we did not support poll dat0, we fulfilled the condition of [1] and a delay of 500 ms was added for every __mmc_switch call. By adding the support of wait_dat0(), we now don't need to mdelay during mmc_init anymore.

2021-10-11sunxi: Clean up inclusions of asm/arch/gpio.hSamuel Holland1-2/+1
As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will remove the asm/arch/gpio.h header. In preparation, clean up the various files that include it. Some files did not contain any GPIO code at all, so this header was completely unused. A few files contained only legacy platform-specific GPIO code for setting up pin muxes. They were left unchanged, as that code will be completely removed by the DM_PINCTRL migration. The remaining files contain some combination of DM_GPIO and legacy GPIO code. For those, switch to including asm/gpio.h (if it wasn't included already). Right now, this header provides both sets of functions, because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the right header to include once the DM_GPIO migration is complete and GPIO_EXTRA_HEADER is no longer needed.

USDHC has register bits(bit[27~20] of register STROBE_DLL_CTRL) for slave sel value. If this register bits value is 0, it needs 256 ref_clk cycles to update slave sel value.

Since the beginning of this driver which was initially for the MPC8379 and MPC8536 SoCs, there is this spurious 1ms delay. According to the comment it should actually be only 8 clock cycles. Esp. during EFI block transfers, this 1ms add up to a significant delay and slows down EFI boot. I couldn't find any mention in the MPC8536 that there should be a delay of 8 clock cycles between commands. The SD card specification mentions that the clock has to be left enabled for 8 cycles after a command or response. But I don't see how this delay will help with this. Go ahead and just remove it. If there will ever be any regression we can introduce a compile time flag, but for now I'd like to keep it simple.
