This patch adds a MFD driver for the JZ4740 ADC unit. The driver is used to demultiplex IRQs and synchronize access to shared registers between the battery, hwmon and (future) touchscreen driver. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
