From 4df591f704a2bebb0ebd7b1593208ab7169857f2 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Thu, 25 Jan 2018 14:10:37 -0600 Subject: ARM: dts: LogicPD Torpedo: Fix I2C1 pinmux commit 74402055a2d3ec998a1ded599e86185a27d9bbf4 upstream. The pinmuxing was missing for I2C1 which was causing intermittent issues with the PMIC which is connected to I2C1. The bootloader did not quite configure the I2C1 either, so when running at 2.6MHz, it was generating errors at time. This correctly sets the I2C1 pinmuxing so it can operate at 2.6MHz Fixes: 687c27676151 ("ARM: dts: Add minimal support for LogicPD Torpedo DM3730 devkit") Signed-off-by: Adam Ford Signed-off-by: Tony Lindgren Signed-off-by: Greg Kroah-Hartman --- arch/arm/boot/dts/logicpd-torpedo-som.dtsi | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/arm/boot/dts/logicpd-torpedo-som.dtsi b/arch/arm/boot/dts/logicpd-torpedo-som.dtsi index 6d89736c7b44..cf22b35f0a28 100644 --- a/arch/arm/boot/dts/logicpd-torpedo-som.dtsi +++ b/arch/arm/boot/dts/logicpd-torpedo-som.dtsi @@ -104,6 +104,8 @@ }; &i2c1 { + pinctrl-names = "default"; + pinctrl-0 = <&i2c1_pins>; clock-frequency = <2600000>; twl: twl@48 { @@ -211,6 +213,12 @@ OMAP3_CORE1_IOPAD(0x21b8, PIN_INPUT | MUX_MODE0) /* hsusb0_data7.hsusb0_data7 */ >; }; + i2c1_pins: pinmux_i2c1_pins { + pinctrl-single,pins = < + OMAP3_CORE1_IOPAD(0x21ba, PIN_INPUT | MUX_MODE0) /* i2c1_scl.i2c1_scl */ + OMAP3_CORE1_IOPAD(0x21bc, PIN_INPUT | MUX_MODE0) /* i2c1_sda.i2c1_sda */ + >; + }; }; &uart2 { -- cgit v1.2.3
