Add support for RK3588 to the rockchip sdhci driver.
Use driver data to handle differences between RK3568 and RK3588:
- Set "Receive original clock source is auto gating" for RK3588.
- Set "Receive clock source is no-inverted" only on RK3568 and "Transmit
clock source is invertion of original clock input" for RK3588.
- Use different txclk_tapnum for HS400 modes on RK3588.
- Configure the CMDOUT reg for HS400 modes for RK3588.
This is based on the mainline linux and vendor kernel driver and have
successfully been tested with 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)
