From fe8d81fe7d9aab6a8e22c8b115eb06b7707087db Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Thu, 2 Aug 2018 20:18:53 -0400 Subject: ARM: dts: qcom: msm8974-hammerhead: add device tree bindings for mpu6515 This patch adds device tree bindings for the mpu6515 to the LG Nexus 5 (hammerhead) phone. Confirmed that the gyroscope / accelerometer (mpu6515), magnetometer (ak8963), and temperature / pressure (bmp280) sensors are available on the phone. Interrupts are not working properly on the ak8963 magnetometer so they are currently not configured. The bmp280 retuns temperature/pressure measurement skipped errors but will reliably work if I run: echo 1 > in_pressure_oversampling_ratio echo 1 > in_temp_oversampling_ratio Signed-off-by: Brian Masney Signed-off-by: Jonathan Marek Signed-off-by: Andy Gross --- .../dts/qcom-msm8974-lge-nexus5-hammerhead.dts | 56 ++++++++++++++++++++++ 1 file changed, 56 insertions(+) (limited to 'arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dts') diff --git a/arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dts b/arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dts index c2dc9d09484a..928affae1885 100644 --- a/arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dts +++ b/arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dts @@ -241,6 +241,24 @@ bias-pull-up; }; }; + + i2c12_pins: i2c12 { + mux { + pins = "gpio87", "gpio88"; + function = "blsp_i2c12"; + drive-strength = <2>; + bias-disable; + }; + }; + + mpu6515_pin: mpu6515 { + irq { + pins = "gpio73"; + function = "gpio"; + bias-disable; + input-enable; + }; + }; }; sdhci@f9824900 { @@ -277,6 +295,44 @@ linux,code = ; }; }; + + i2c@f9968000 { + status = "ok"; + pinctrl-names = "default"; + pinctrl-0 = <&i2c12_pins>; + clock-frequency = <100000>; + qcom,src-freq = <50000000>; + + mpu6515@68 { + compatible = "invensense,mpu6515"; + reg = <0x68>; + interrupts-extended = <&msmgpio 73 IRQ_TYPE_EDGE_FALLING>; + vddio-supply = <&pm8941_lvs1>; + + pinctrl-names = "default"; + pinctrl-0 = <&mpu6515_pin>; + + i2c-gate { + #address-cells = <1>; + #size-cells = <0>; + ak8963@f { + compatible = "asahi-kasei,ak8963"; + reg = <0x0f>; + // Currently only works in polling mode. + // gpios = <&msmgpio 61 0>; + vid-supply = <&pm8941_lvs1>; + vdd-supply = <&pm8941_l17>; + }; + + bmp280@76 { + compatible = "bosch,bmp280"; + reg = <0x76>; + vdda-supply = <&pm8941_lvs1>; + vddd-supply = <&pm8941_l17>; + }; + }; + }; + }; }; &spmi_bus { -- cgit v1.2.3
