From 8e75eed6173232b57605a18ed3dbbd3f17aed293 Mon Sep 17 00:00:00 2001 From: Ryan Salsbury Date: Mon, 16 Sep 2024 17:49:21 -0700 Subject: [PATCH] ath79: fix I2C pins on GL-AR750 Change I2C pin flags to GPIO_ACTIVE_HIGH and change SDA to GPIO1. On my late production GL-AR750 (purchased 2024): SCL = GPIO16 SDA = GPIO1 Bug report: I2C bus doesn't work in GL-AR750 https://github.com/openwrt/openwrt/issues/16319 Signed-off-by: Ryan Salsbury Link: https://github.com/openwrt/openwrt/pull/16406 Signed-off-by: Robert Marko (cherry picked from commit 2e626ae2d2488f2d3708d3aed57eea7a1402f00e) Signed-off-by: Ryan Salsbury Link: https://github.com/openwrt/openwrt/pull/16446 Signed-off-by: Hauke Mehrtens --- target/linux/ath79/dts/qca9531_glinet_gl-ar750.dts | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/target/linux/ath79/dts/qca9531_glinet_gl-ar750.dts b/target/linux/ath79/dts/qca9531_glinet_gl-ar750.dts index 60bd2922a2..abf1223cf6 100644 --- a/target/linux/ath79/dts/qca9531_glinet_gl-ar750.dts +++ b/target/linux/ath79/dts/qca9531_glinet_gl-ar750.dts @@ -61,8 +61,8 @@ i2c { compatible = "i2c-gpio"; - sda-gpios = <&gpio 17 GPIO_ACTIVE_LOW>; - scl-gpios = <&gpio 16 GPIO_ACTIVE_LOW>; + sda-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>; + scl-gpios = <&gpio 16 GPIO_ACTIVE_HIGH>; }; }; -- 2.30.2
