| Message-ID | <rZrUZ-4X3-3@gated-at.bofh.it> |
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 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.
