The patch set is to enable Vybrid VF610 ADC driver. It is the init version. Please see the Reference Manual of the ADC: http://cache.freescale.com/files/32bit/doc/ref_manual/VYBRIDRM.pdf?fpsp=1&WT_TYPE= Reference%20Manuals&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation Feature: * Enable Vybrid vf610 board ADC0 in dts file. * ADC driver only support software trigger for the init version. * ADC configuration support dts set. Note: Since the ADC IP is used for Freescale Vybrid VF610, i.MX6SLX, i.MX7 serial sillicons, we name the driver name to "imx_adc". Test: * Vybrid vf610-twr board connect ADC0 SE5 pin to one sliding rheostat for ADC test, so after kernel up, get the voltage from sys interface: cat /sys/bus/iio/devices/iio\:device0/in_voltage5_raw cat /sys/bus/iio/devices/iio\:device0/in_voltage_scale The current voltage = in_voltage5_raw * in_voltage_scale (uV).
