[PATCH 0/9] rockchip: pinctrl: Minor fixes and add support for pinmux status cmd

[Kever Yang]

Hi Jonas,

     Could you spit this patch in two part, one with fixes only, which I 
can merge it for master directly,

and another part for new feature and together with "Add gpio request" 
for next?


Thanks,

- Kever
