3d821a1747 iio: exynos_adc: use indio_dev->dev structure to handle child nodes
Using pdev->dev with device_for_each_child() would iterate over all
of the children of the platform device and delete them.
Thus, causing crashes during module unload.

We should be using the indio_dev->dev structure for
registering/unregistering child nodes.

c619653d77 adc: exynos_adc: Convert to devm_ioremap_resource()
Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.

927b4dc3e4 iio: exynos_adc: fix wrong structure extration in suspend and resume
The exynos_adc device structure was wrongly extracted from the dev*
correcting the same.

Using the regular conversion of
struct device* -> struct platform_device* -> struct exynos_adc* seems wrong.
Instead we should be doing
struct device* -> struct iio_dev* -> struct exynos_adc*

1ba0686b2b iio: exynos_adc: Remove redundant of_match_ptr macro
exynos_adc is a DT only driver and exynos_adc_match table is always
compiled in. Hence remove the macro.

bb916ebbea iio: adc: Add dt support for turning on the phy in exynos-adc
Without this change the exynos adc controller needed to have its phy
enabled in some out-of-driver C code.  Add support for specifying the
phy enable register by listing it in the reg list.
