[PATCH v2 0/5] iio: adc: bcm_iproc_adc: use device-managed resources

[mdshahid03]

From: Mohammad Shahid <mdshahid03@xxxxxxxxx>

Changes since v1:

- Sort headers and make the driver IWYU compliant.
- Use devm_clk_get_enabled() and devm_add_action_or_reset() for
- clock and ADC cleanup.
- Use devm_mutex_init() and devm_iio_device_register(), removing
  the manual cleanup paths and remove() callback.

I checked the history of IPROC_ADC_AUXIN_SCAN_ENA and the related
iProc touchscreen driver. There is no documented dependency requiring
the bit to be cleared before tsc_clk is enabled.

I also checked the touchscreen driver's shared-register handling. It
enables tsc_clk before configuring the shared REGCTL2, and its
history does not indicate an ordering requirement involving
IPROC_ADC_AUXIN_SCAN_ENA.

Therefore, devm_clk_get_enabled() is used as suggested.

linux/delay.h is retained because the driver directly uses udelay().
