Subject[PATCH v3] arm64: dts: mt8173: add mmsel clocks for 4K support
Date
If MT8173 can support HDMI 4K resoultion, the
VENCPLL should be configured to 800MHZ.
We didn't set VENCPLL directly, we set the
mm_sel to 400MHz statically in the board device tree.

Changes since v2:
- Align the clocks of dpi0 node.

Changes since v1:
- Do not set the VENCPLL by clk_set_rate
at display driver.
- Configure the mm_sel to 400MHz statically
in the board device tree.
