This series fixes eMMC HS400 modes on RK3568 and add support for RK3588.
It has been tested with rock-3a-rk3568/rock5b-rk3588 defconfig and
CONFIG_MMC_HS200_SUPPORT=y CONFIG_MMC_HS400_SUPPORT=y CONFIG_MMC_HS400_ES_SUPPORT=y CONFIG_MMC_SPEED_MODE_SET=y
using the following command to switch mode and then read 512 MiB of data from eMMC into memory,
=> mmc dev 0 0 <mode> && mmc info && mmc read 10000000 2000 10000
for each of the modes below.
0 = MMC legacy 1 = MMC High Speed (26MHz) 3 = MMC High Speed (52MHz) 4 = MMC DDR52 (52MHz) 10 = HS200 (200MHz) 11 = HS400 (200MHz) 12 = HS400ES (200MHz)
All reads have reported OK, prior to this some of these modes worked and others failed.
Patch 1-2 fixes an issue with high-speed bit and uhs speed mode field. Patch 3-6 refactors the rk3568 driver to use set_clock and config_dll ops, so that clocks and regs are changed when output clock is disabled. Patch 7-10 continues refactoring and simplification of the driver. Patch 11-12 updates tap and delay values to fix HS400 modes on RK3568. Patch 13-15 adds support for RK3588 to driver and device tree. Patch 16-17 adds workarounds needed to use PIO mode in SPL to successfully load TF-A into SRAM when booting from eMMC on RK3588.
Note that this series does not include any change to defconfigs to enable HS200/HS400/HS400ES modes.
