[PATCH v3 0/8] RK3588 ADC support

[Shreeya Patel <shreeya.patel@collabora.com>]

This patch series adds ADC support for RK3588 and updates
the DT bindings for the same.

To test ADC support on Rock 5B board, a voltage divider circuit
was created using the gpio pin 22 ( SARADC_IN4 ) and few more
tests were ran for testing the buffer and trigger support using
the iio_generic_buffer tool.

Changes in v3
  - Add bitfield.h header file in patch 2.
  - Add a Reviewed-by tag in patch 2.
  - Do not remove clock enabling and disabling from the suspend and
    resume functions respectively in patch 3

Changes in v2
  - Add from address in patches 1 and 2.
  - Create separate patches for adding new device support and changes to
    the old device code.
  - Make use of FIELD_PREP in patch 2.
  - Move the enablement of clocks at it's original position in patch 3
  - Add Reviewed-by tag in patches 4 and 5.
  - Add an Acked-by tag in patch 8.
