iio: adc: exynos_adc: Add support for s3c24xx ADC
This patch add support for s3c2410/s3c2416/s3c2440/s3c2443 ADC. The s3c24xx is alomost same as ADCv1. But, There are a little difference as following: - ADCMUX register address - ADCDAT mask (10 bit or 12 bit ADC resolution according to SoC version) - s3c24xx/s3c64xx has not included ADC_PHY enable register Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
