iio: add adjd_s311 I2C digital color sensor drivertogreg-3.6atogreg
sensor has 4 channels (10-bit each, R/G/B and clear), sensitivity and gain is controlled in the driver by ext_info integration_time and CHAN_INFO_HARDWAREGAIN driver supports triggered buffer and IIO_CHAN_INFO_RAW to get the sensor data v5: address comments by Jonathan Cameron * use macro for channel declaration * get timestamp right before measurement * cleanups v4: address comments by Lars-Peter Clausen * make sure trigger handler is exited with iio_trigger_notify_done() and IRQ_HANDLED * kfree()/kalloc() -> krealloc() v3: * fix warnings v2: address comments by Lars-Peter Clausen * buffer allocation now in update_scan_mode instead of in trigger handler * simplify trigger code (assume active_scan_mask is not empty, use for_each_set_bit, use iio_push_to_buffer) * reorder entry in Makefile and Kconfig * fix remove Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
