The rk3528.dtsi in upstream Linux v6.13-dts is very basic and only
contain cpu nodes and uart nodes. There is a pending series to add basic
CRU support.

This series is going a little bit ahead of upstream Linux and add bare
minimum to get working boot from eMMC and SD-card. Something that
require working CRU and pinctrl.

Guess we can always wait on full support of CRU, pinctrl, sdhci and
sdmmc to land in upstream Linux before we add support for the SoC in
U-Boot.

Jonas
