rockchip: mmc: rockchip_dw_mmc: add rk3066/rk3188 support
The Rockchip SoCs rk3066/rk3188 have MMC DT nodes
with as compatible string "rockchip,rk2928-dw-mshc".
Add OF_PLATDATA support to the existing driver with
help of a DM_DRIVER_ALIAS.
This type needs a permanent enabled fifo.
The other Rockchip SoCs always have the property
"u-boot,spl-fifo-mode" in the MMC DT nodes,
because MMC to SRAM can't do DMA.
Make this property a requirement for MMC OF_PLATDATA
structures. The property "fifo-mode" must be added
for all other compile modes.
