This series add initial support for the Rockchip RK3528 SoC.
Clk, pinctrl and rng drivers have been imported from vendor U-Boot with minor adjustments and fixes.
Upstream DT for RK3528 is at a very basic state at the moment and this series instead add a few missing nodes to -u-boot.dtsi files to have a bootable system.
Features tested on a ArmSoM Sige1: - SD-card boot - eMMC boot
Features tested on a Radxa E20C v1.104: - SD-card boot - eMMC boot
Features tested on a Radxa ROCK 2A v1.202: - SD-card boot
