From 7f8327bd376c54e205d98885a0ba9a31c053faeb Mon Sep 17 00:00:00 2001 From: Richard Oliver Date: Tue, 25 Feb 2025 15:06:23 +0000 Subject: [PATCH] dts: Add hogs for RP1 GPIO 46/48 on CM5 On Pi5 5, GPIOs 46/48 are made available on the 'CAM/DISP 1' connector as 'CD1_IO0_MICCLK'/'CD1_IO1_MICDAT1'. These GPIOs are not connected on CM5. Add hogs for GPIO 46/48 on CM5 to prevent camera drivers from inadvertently using them when connected to 'CAM/DISP 1' Signed-off-by: Richard Oliver --- arch/arm64/boot/dts/broadcom/bcm2712-rpi-cm5.dtsi | 12 ++++++++++++ 1 file changed, 12 insertions(+) --- a/arch/arm64/boot/dts/broadcom/bcm2712-rpi-cm5.dtsi +++ b/arch/arm64/boot/dts/broadcom/bcm2712-rpi-cm5.dtsi @@ -700,6 +700,18 @@ spi10_cs_pins: &spi10_cs_gpio1 {}; function = "vbus1"; pins = "gpio42", "gpio43"; }; + + micclk1_hog { + gpio-hog; + gpios = <46 GPIO_ACTIVE_HIGH>; + output-high; + }; + + micdat1_hog { + gpio-hog; + gpios = <48 GPIO_ACTIVE_HIGH>; + output-high; + }; }; / {
