From 676dc1013a79aa317031151d474ba46564aa125b Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 29 Nov 2021 13:11:56 +0000 Subject: [PATCH] dtoverlays: Drop i2c baudrate for Pi 7inch DSI screen to 50kHz Whilst investigations continue as to why the 7" DSI screen doesn't work on Pi3 with KMS, drop the I2C baudrate to 50kHz as that seems to be a reliable workaround. This will be reverted once the full issue is understood. https://github.com/raspberrypi/linux/issues/4686 Signed-off-by: Dave Stevenson --- arch/arm/boot/dts/overlays/vc4-kms-dsi-7inch-overlay.dts | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/boot/dts/overlays/vc4-kms-dsi-7inch-overlay.dts b/arch/arm/boot/dts/overlays/vc4-kms-dsi-7inch-overlay.dts index 5e1700d0367a0..5b6f82aaa6fbc 100644 --- a/arch/arm/boot/dts/overlays/vc4-kms-dsi-7inch-overlay.dts +++ b/arch/arm/boot/dts/overlays/vc4-kms-dsi-7inch-overlay.dts @@ -95,6 +95,7 @@ target = <&i2c0if>; __overlay__ { status = "okay"; + clock-frequency = <50000>; }; };
