[PATCH V3,0/8] make mt7623 clock of HDMI stable

[CK Hu]

Hi, Wangyan:

How do you prove that this series would make mt7623 HDMI clock more
stable? By experience result? I would like to prove it by the source
code.

Does 'stable' means that hardware could generate the frequency most
close to the target frequency? If it does, I think you could compare the
frequency generated by original code and applying this series for all
the usually-used frequency. I also need you to show the clock tree and
all setting of each divider so we could review that is this series good
enough. Also, describe these in cover latter.

You have mail to dri-devel [1] and linux-mediatek [2], but these patches
does not show in web site. Maybe your mail is not plain text, please fix
this and resend patches.
