[Alibek Omarov]

> Based on Alibek Omarov's earlier posting [1], with the changes below.

Hi, I'm Alibek Omarov and thanks for picking up my patches. I didn't
had time to finish them and these days I don't work on hardware that
uses any of Rockchip SoCs. However, if I'm not wrong, it's still used
in production and I had report from Jakob Loeschke (added in CC) who
confirmed it worked in their setup as well.

Thanks.
