From: Wangyan Wang <wangyan.w...@mediatek.com>
V8 adopt maintainer's suggestion.
Here is the change list between V7 & V8
1. Make title more clear in patch commit message.
2. To make MT2701 HDMI stable, TVDPLL should not be adjusted and
it's the parent clock of HDMI phy, so HDMI phy could not adjust parent
rate. there are 3 steps to make MT2701 HDMI stable.
1). remove flag CLK_SET_RATE_PARENT for mt2701 hdmi phy to not propagate
rate change to parent in "drm/mediatek: remove flag ...".
2). Using new factor for tvdpll in mt2701 to match divider of DPI in
mt2701 in "drm/mediatek: using new...".
3). No change parent rate in round_rate() for mt2701 hdmi phy in
"drm/mediatek: no change parent...".
3. Recalculate the rate of this clock, by querying hardware to
make implementation of recalc_rate() to match the definition.
