This is the third step to make MT2701 HDMI stable. We should not change the rate of parent for hdmi phy when doing round_rate for this clock. The parent clock of hdmi phy must be the same as it. We change it when doing set_rate only. Signed-off-by: Wangyan Wang <wangyan.wang@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
