This series add initial support for the Rockchip RK3506 SoC. Clk and pinctrl drivers have been imported from vendor U-Boot with some adjustments and fixes.
Upstream DT is currently not existing for RK3506, so this series does not add support for any new boards, it only add initial arch support. Please see my U-Boot rk3506 branch at [1] for a few more commits that add DTs and defconfig for e.g. Luckfox Lyra variants and ArmSoM Forge1. With this series, board DTs and defconfigs it should be possible to boot into U-Boot proper (without OP-TEE) and still have support for MMC, Ethernet, OTP, RNG, LEDs, buttons and USB gadget/host.
