Cover letter [PATCH 0/4] arm64: add initial support for the Rockchip rk3368

Hi, Heiko

Could I test the code on rk3368 STB such as EKB368, CSA90? Is there some documents about it?

Thanks

This adds initial support for the new rk3368 ARM64 soc from Rockchip.

Overall it looks like someone dropped some A53 cores into a rk3288, so it shares a lot of peripherals that only differ in details. Therefore stuff like the mmc, usb, spi, i2c controllers work out of the box. The support for the gmac already made it into the merge window as well as the pinctrl support.

Interestingly, in its core the rk3368 seems trying to be a model student with psci for smp and using scpi for ddr frequency scaling, although I currently do not understand how the mailbox works yet. The display controllers also are only minimally different so I'm hopefully to have working graphics in the near-ish future :-)

As mentioned in the dts patch, this series depends on the dt-binding header for the clock ids, so will need a shared branch once this is ready.
