Subject: [PATCH] phy/rockchip: inno-hdmi: force set_rate on power_on
Regular 8-bit and Deep Color video formats mainly differ in TMDS rate and
not in pixel clock rate.
When the hdmiphy clock is configured with the same pixel clock rate using
clk_set_rate() the clock framework do not signal the hdmi phy driver
to set_rate when switching between 8-bit and Deep Color.
This result in pre/post pll not being re-configured when switching between
regular 8-bit and Deep Color video formats.
Fix this by calling set_rate in power_on to force pre pll re-configuration.

Subject: [PATCH] mmc: core: set initial signal voltage on power off
Some boards have SD card connectors where the power rail cannot be switched
off by the driver. If the card has not been power cycled, it may still be
using 1.8V signaling after a warm re-boot. Bootroms expecting 3.3V signaling
will fail to boot from a UHS card that continue to use 1.8V signaling.
Set initial signal voltage in mmc_power_off() to allow re-boot to function.
This fixes re-boot with UHS cards on Asus Tinker Board (Rockchip RK3288),
same issue have been seen on some Rockchip RK3399 boards.
I am sending this as a RFC because I have no insights into SD/MMC subsystem,
this change fix a re-boot issue on my boards and does not break emmc/sdio.
Is this an acceptable workaround? Any advice is appreciated.

Subject: [PATCH] arm64: dts: rockchip: Add sdmmc_ext for RK3328
RK3328 SoC has a fourth mmc controller called SDMMC_EXT. Some
boards have sdio wifi connected to it. In order to use it
one would have to add the pinctrls from sdmmc0ext group which
is done on board level.
