If anyone has any objections, please let me know. ------------------ From: Carl Frederik Werner 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: Kamal Mostafa --- 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 c792391..cbcbc8a 100644 --- a/arch/arm/boot/dts/omap3-beagle.dts +++ b/arch/arm/boot/dts/omap3-beagle.dts @@ -204,7 +204,7 @@ 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 */ >; };
