Question for Heiko:

This file is put in the arm64 directory.
Is it useful for ARM as well?
Should the ARM directory have it's own or use a long include?

ARM:
#include "../../../arm64/boot/dts/rockchip/rockchip-pinconf.dtsi"

arm64:
#include "rockchip-pinconf.dtsi"

Is it complete or does it need more items?
(Who's going to change that?)
