ASoC: codecs: msm8916-wcd-analog: get micbias voltage from dt
This patch adds bindings in DT to provide required micbias voltage which could be specific to board. With this new binding, now the mic bias voltage is left at hardware default value if the device tree does not specify any mic bias voltage value. Correct micbias value is required for mbhc buttons to work. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
