[PATCH v6 0/3] iio: imx8qxp-adc: Add driver support for NXP IMX8QXP ADC

[Cai Huoqing]

The NXP i.MX 8QuadXPlus SOC has a new ADC IP. These patches add
driver support for this ADC.

dt-bindings: iio: adc:
v1->v2:
        *Fix some indentation issues.
        *Mark status as okay.
        *Change clock2 source.
v3->v4:
        *Remove 'status' from examples.
        *Remove unused 'state'.
        *Remove interrupts-parent.
        *Change num of address/size-cells from 1 to 2.
v4->v5:
        *Remove unused properties.

iio: imx8qxp-adc:
v1->v2:
	*Squash patches 1, 2, 3, and 5 into a single patch.
	*Add device specific prefix.
	*Remove the brackets around individual numbers.
	*Make use of FIELD_PREP() and FIELD_GET().
	*Remove a lot of cache values.
	*Replace mlock with adc->lock.
	*Move adc->value read from isr to the completion.
	*Set pm_runtime_disable/_put_noidle() before adc_disable.
	*Add error handler-err_disable_reg/err_unprepare_clk.
v2->v3:
	*Add "return 0" to adc_runtime_resume().
v3->v4:
	*Sort header file declarations in alphabetical order.
	*Remove explicitly cast from "void *".
	*Make use of dev_err_probe().
	*Add some blank lines to help readability.
v4->v5:
	*Update commit message.
	*Remove unused headers.
	*Wrap imx8qxp_adc_read_raw() at a shorter line length that helps readability.
	*Deal with clock/regulator in probe/remove().
	*Use ADC_DRIVER_NAME instead of dev_name(dev).
	*Don't use dev_error_probe() without returning -PROBE_DEFER.
v5->v6:
	*Rename the error path labels to indicate the action that will be performed.
