From: Wangyan Wang <wangyan.wang@...iatek.com>

V7 adopt maintainer's suggestion.
Here is the change list between V6 & V7

1. use readl directly & delete hdmi_phy->pll_rate in
mtk_hdmi_pll_recalc_rate(). 
in "drm/mediatek: recalculate hdmi ..."

2. detele mtk_hdmi_phy_read() in mtk_hdmi_phy.c.
in "fix the rate of parent for hdmi phy in MT2701"

3. optimize mtk_hdmi_pll_round_rate().
in "fix the rate of parent for hdmi phy in MT2701"

chunhui dai (6):
  drm/mediatek: recalculate hdmi phy clock of MT2701 by querying
    hardware
  drm/mediatek: move the setting of fixed divider
  drm/mediatek: using different flags of clk for HDMI phy
  drm/mediatek: fix the rate and divder of hdmi phy for MT2701
  drm/mediatek: using new factor for tvdpll in MT2701
  drm/mediatek: fix the rate of parent for hdmi phy in MT2701
