There is no dependence between this and that patch, but I would assume the hardware won't work until both are present.

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 <masneyb@onstation.org> Signed-off-by: Jonathan Marek <jonathan@marek.ca> --- 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(+)
