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 --- I'll send follow up patch(es) once I investigate why the skipped errors are occurring with the bmp280 with the default oversampling ratios. .../qcom-msm8974-lge-nexus5-hammerhead.dts | 56 +++++++++++++++++++ arch/arm/boot/dts/qcom-msm8974.dtsi | 11 ++++ 2 files changed, 67 insertions(+) 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 { diff --git a/arch/arm/boot/dts/qcom-msm8974.dtsi b/arch/arm/boot/dts/qcom-msm8974.dtsi index d9019a49b292..cebb6ae9143a 100644 --- a/arch/arm/boot/dts/qcom-msm8974.dtsi +++ b/arch/arm/boot/dts/qcom-msm8974.dtsi @@ -737,6 +737,17 @@ dma-names = "tx", "rx"; }; + blsp_i2c12: i2c@f9968000 { + status = "disabled"; + compatible = "qcom,i2c-qup-v2.1.1"; + reg = <0xf9968000 0x1000>; + interrupts = <0 106 IRQ_TYPE_NONE>; + clocks = <&gcc GCC_BLSP2_QUP6_I2C_APPS_CLK>, <&gcc GCC_BLSP2_AHB_CLK>; + clock-names = "core", "iface"; + #address-cells = <1>; + #size-cells = <0>; + }; + spmi_bus: spmi@fc4cf000 { compatible = "qcom,spmi-pmic-arb"; reg-names = "core", "intr", "cnfg"; -- 2.17.1
