2017-05-24reset: hi6220: Set module license so that it can be loadedGravatar Jeremy Linton 1-0/+2
The hi6220_reset driver can be built as a standalone module yet it cannot be loaded because it depends on GPL exported symbols. Lets set the module license so that the module loads, and things like the on-board kirin drm starts working.

2016-06-29reset: hisilicon: Change to syscon register accessGravatar Chen Feng 1-40/+45
There are two reset controllers in hi6220 SoC: The peripheral reset controller bits are part of sysctrl registers. The media reset controller bits are part of mediactrl registers. So change register access to syscon way. And rename current reset controller to peripheral one.
