MSM8916 has another I2C QUP controller that can be enabled on GPIO 2 and 3. Add blsp_i2c1 to msm8916.dtsi and disable it by default. Signed-off-by: Stephan Gerhold <stephan@gerhold.net> --- On samsung-a2015 there is an external TFA9895 speaker amplifier connected to blsp_i2c1. There isn't a proper mainline driver for it (yet?), but it's nice to have the I2C bus in mainline at least. --- arch/arm64/boot/dts/qcom/msm8916-pins.dtsi | 24 ++++++++++++++++++++++ arch/arm64/boot/dts/qcom/msm8916.dtsi | 15 ++++++++++++++ 2 files changed, 39 insertions(+)
