[PATCH v5 0/3] add imx93 adc support

[haibo.chen@nxp.com]

From: Haibo Chen <haibo.chen@nxp.com>

V5:
  -For ADC driver, use dev_err_probe() to replace dev_err() in dev_err_probe(). 
  -Add imx93_adc_power_down() in the probe error path.
  -Re-order the function in imx93_adc_remove(), make them inverse in probe().
  -Remove the pm_runtime_get_sync(dev) in imx93_adc_remove(), because this driver
   enable the pm_runtime autosuspend feature, and config the delay as 50ms. So when
   called imx93_adc_remove(), this device still in runtime resume state, no need to
   force resume the device back.
  -no changes for binding doc and dts.

V4:
  For ADC driver, re-define the ADC status show the relation to specific register bit.
  Redo the imx93_adc_remove(), change the return error sequence in imx93_adc_read_raw(),
  and use a direct string for indio_dev->name.
  For dt-bings, change the commit title and add maintainer's reviewed by tag
  For dts, no change.

V3:
  For dt-bings, add some change according to review comments, and pass dt_binding_check.
  For dts, add #io-channel-cells = <1>; to pass dtbs_check
  For ADC driver, no change.

V2:
  For ADC driver, add change according to matainer's commets.
