Subject: [PATCH v3 2/9] ARM: dts: qcom: msm8974-hammerhead: add device tree bindings for mpu6515
Date: Thu, 2 Aug 2018 20:18:53 -0400 [thread overview]
Message-ID: <20180803001900.25371-3-masneyb@onstation.org> (raw)
In-Reply-To: <20180803001900.25371-1-masneyb@onstation.org>
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.
