Pach 1-3 looks good, but could be squashed in one patch. Please try to come up
with a more descriptive commit message. Rule of thumb is to explain why we need
a patch not what the patch does.

Hi Yongqiang,

There is 8192 mmsys compatible data in [1], but seems to lack of it in
this patch, because mm clock driver will be bound to platform device 
in mtk_mmsys_probe.

Yes, you should add a match in of_match_mtk_mmsys[] for the compatbile. The
clock driver should be implemented as a platform device.
