From 2a440b8f3a7123170180bfe16b2f1a5be4ac2e5f Mon Sep 17 00:00:00 2001 From: Carl Frederik Werner Date: Wed, 2 Sep 2015 10:07:57 +0900 Subject: [PATCH] ARM: dts: omap3-beagle: make i2c3, ddc and tfp410 gpio work again commit 3a2fa775bd1d0579113666c1a2e37654a34018a0 upstream. Let's fix pinmux address of gpio 170 used by tfp410 powerdown-gpio. According to the OMAP35x Technical Reference Manual CONTROL_PADCONF_I2C3_SDA[15:0] 0x480021C4 mode0: i2c3_sda CONTROL_PADCONF_I2C3_SDA[31:16] 0x480021C4 mode4: gpio_170 the pinmux address of gpio 170 must be 0x480021C6. The former wrong address broke i2c3 (used by hdmi ddc), resulting in kernel message: omap_i2c 48060000.i2c: controller timed out Fixes: 8cecf52befd7 ("ARM: omap3-beagle.dts: add display information") Signed-off-by: Carl Frederik Werner Signed-off-by: Tony Lindgren Signed-off-by: Luis Henriques --- arch/arm/boot/dts/omap3-beagle.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/omap3-beagle.dts b/arch/arm/boot/dts/omap3-beagle.dts index 3c3e6da1deacd..3595d1ceae0cf 100644 --- a/arch/arm/boot/dts/omap3-beagle.dts +++ b/arch/arm/boot/dts/omap3-beagle.dts @@ -176,7 +176,7 @@ tfp410_pins: pinmux_tfp410_pins { pinctrl-single,pins = < - 0x194 (PIN_OUTPUT | MUX_MODE4) /* hdq_sio.gpio_170 */ + 0x196 (PIN_OUTPUT | MUX_MODE4) /* hdq_sio.gpio_170 */ >; }; -- 2.47.3
