[Haibo Chen]

This patch set add imx7d adc driver support.

Changes in v5:
-call imx7d_adc_power_down() in driver probe when iio_device_register() failed
-handle with adc channel conversion timeout in imx7d_adc_isr()

Changes in v4:
-sort the include head file alphabetically
-really just clear the bit 31 of register REG_ADC_CH_A\B\C\D_CFG1 
 in function imx7d_adc_sample_rate_set()
-add document in imx7d_adc_isr() to clarify the clear operation
-add function imx7d_adc_power_down()
-adjust the format of the code and add some small changes

Changes in v3:
-move down the irq request in probe()
-remove the property 'num-channels' in dts
-remove some unused head file
-add clear register operation in imx7d_adc_isr()

Changes in v2:
-prefix defines with IMX7D_ for all the register
-use BIT macro to define a single bit
-remove the dma_en from struct adc_feature which is not support currently
-use static const array to replace the switch case code
