This doesn't work for rk3399, as the pd_vio doesn't have any clocks
attached.

[    0.713241] rockchip-pm-domain 
ff310000.power-management:power-controller: failed to handle node 
pd_vio: -12
[    0.714615] rockchip-pm-domain: probe of 
ff310000.power-management:power-controller failed with error -12


I think Jeffy's v2 is coming, so I assume you will drop this version?
