The hdmitx_dig_cts clock is not a child of tvdpll_445p5m, but is an output of the HDMI PHY module, which is routed back into the TOP clock module for further divison and muxing. - The hdmi_sel mux defaults to its 26 MHz input - switch it to the HDMI PHY PLL output. --- arch/arm64/boot/dts/mediatek/mt8173.dtsi | 75 ++++++++++++++++++++++++++++++++ 1 file changed, 75 insertions(+)
