2014-08-04ASoC: adau1977: Fix truncation warning on 64 bit architecturesMark Brown1-1/+1
Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant with all bits set which on 64 bit architectures needs to be truncated to an unsigned int, generating a warning. Add an explicit cast since we know this is OK. Signed-off-by: Mark Brown <broonie@linaro.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>
2014-02-19ASoC: Add ADAU1977 CODEC driverLars-Peter Clausen1-0/+1018
This patch adds support for the ADAU1977, ADAU1978 and ADAU1979 audio CODEC devices. They are a family of 4-channel differential input audio ADC devices. They can be connected to either a SPI or I2C bus. The driver is implemented in three modules, one main module (adau1977.ko) which implements the device logic and one module each for SPI (adau1977-spi.ko) and I2C (adau1977-i2c.ko) bus access.
