[PATCH 0/6] mci: rockchip-dwcmshc: add HS200 support

[Sascha Hauer]

At least on RK3588 the dwcmshc core doesn't have an internal clock
divider, we fully rely on the clock tree to configure the MMC clock.
By default the clock comes from the 24MHz oscillator. For higher MMC
clocks we have to reparent to a PLL clock, but if we do this once the
6bit divider iss not enough to scale down to the 400kHz MMC
initialization clock. This means we must dynamically reparent the clock.
This series adds support for finding the best divider/mux combination
for composite clocks.

This series also adds some fixes to the dwcmshc driver which used to
timeout on writing sometimes.
