Patches 2-4 are in my domain so I'll get them after -rc1, but in theory the gpio binding should go through the gpio tree. Heiko

Ah, thanks for the heads up. I guess we need to agree on one then. Bartosz, gpio tree or the rockchip tree for patches 1+2? ;-) Heiko

Current dts files with RK3328 GRF 'gpio' nodes are manually verified. In order to automate this process rk3328-grf-gpio.txt has to be converted to YAML. Rename 'grf-gpio' nodename to 'gpio'.
