ASoC: tlv320adcx140: Fix bias config values
The device tree binding declares the ti,mic-bias-source and the ti,vref-source properties as u32. The code reads them as u8 which is incorrect. Since the device tree binding indicates them as u32 the conde needs to be updated to read u32. In addition the bias source needs to be shifted 4 bits to correctly write the register. driver family") Fixes: 37bde5acf040 ("ASoC: tlv320adcx140: Add the tlv320adcx140 codec Signed-off-by: Dan Murphy <dmurphy@ti.com> Link: https://lore.kernel.org/r/20200513142807.11802-1-dmurphy@ti.com Signed-off-by: Mark Brown <broonie@kernel.org>
