This changes resolves an issue when using -the legacy firmware display driver where the DVP caused the 108 MHz -clock in HDMI TX to be gated off when Linux started. This effectively -stopped the firmware from being able to change the HDMI analog PHY -registers. - -Add a fragment to re-enable this in vc4-kms-v3d-pi4-overlay ---- - arch/arm/boot/dts/bcm2711-rpi.dtsi | 1 + - arch/arm/boot/dts/overlays/vc4-kms-v3d-pi4-overlay.dts | 7 +++++++ - 2 files changed, 8 insertions(+) - ---- a/arch/arm/boot/dts/bcm2711-rpi.dtsi -+++ b/arch/arm/boot/dts/bcm2711-rpi.dtsi -@@ -46,6 +46,7 @@ - clocks = <&clk_108MHz>; - #clock-cells = <1>; - #reset-cells = <1>; -+ status = "disabled"; - }; - - hdmi0: hdmi@7ef00700 { ---- a/arch/arm/boot/dts/overlays/vc4-kms-v3d-pi4-overlay.dts -+++ b/arch/arm/boot/dts/overlays/vc4-kms-v3d-pi4-overlay.dts -@@ -145,6 +145,13 @@ - }; - }; - -+ fragment@20 { -+ target = <&dvp>; -+ __overlay__ { -+ status = "okay"; -+ }; -+ }; -+ - __overrides__ { - audio = <0>,"!17"; - audio1 = <0>,"!18"; |
