| |
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.
Signed-off-by: Bibby Hsieh <bibby.hsieh@mediatek.com> --- 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. --- arch/arm64/boot/dts/mediatek/mt8173.dtsi | 2 ++ 1 file changed, 2 insertions(+)
