PATCH 1/1 ARM64: dts: amlogic: Add basic support for Amlogic S905X

From: Carlo Caione <[email protected]>

This patch introduces the basic support for the Amlogic S905X (Meson GXL) and for the Amlogic evaluation board P212.
No documentation has been released yet for this SoC, so for now only the bare minimum has been added in the DT.

I don't have documentation either, but looks sane to me.

With the recent driver progress have you checked whether /memory at 0 actually works or whether U-Boot gives us a /memory node that Linux is using instead?

Hardkernel have released a datasheet for the S905:

HTH.

Cheers,
