Subject: [PATCH 0/5] clk: meson8b: video clock tree updates

Hi Jerome,

this is a small set of updates for the video clocks. I have verified
these patches to be able to generate the video clocks for 1080P, 720P
and a few other video modes.

The main "mystery" is still how the rate doubling happens. However,
that doesn't affect these patches as with this rate doubling the
"hdmi_pll_lvds_out" (which is a parent of this tree) is doubled as
well. That's why I am sending these patches because even with this
unknown part about rate doubling they will still be valid once that
unknown part has been figured out.

Martin Blumenstingl (5):
  clk: meson: meson8b: don't use MPLL1 as parent of vclk_in_sel
  clk: meson: meson8b: define the rate range for the hdmi_pll_dco clock
  clk: meson: meson8b: add the video clock divider tables
  clk: meson: meson8b: add the HDMI PLL M/N parameters
  clk: meson: meson8b: add the vid_pll_lvds_en gate clock
