Hi All,

This patch series adds ADC support for Renesas RZ/G2L family.

Patches apply on top of v5.14-rc2.

Cheers,
Prabhakar

Changes for v4:
* Fixed registering action to assert resets on failure/remove
  as reported by Philip.
* Fixed review comments suggested by Jonathan.
* Included RB tag from Rob for patch 1/3
* Note DTS patch applies on top of https://git.kernel.org/pub/scm/
  linux/kernel/git/geert/renesas-devel.git/log/
  ?h=renesas-arm-dt-for-v5.15

Changes for v3 (as requested by Jonathan):
* Made use of FIELD_PREP()
* Renamed _CLEAR to _MASK and inverted inline as required
* Moved |= pair's on same lines
* Made use of sysfs_emit() while reading the labels
* Used for_each_bit_set() in rzg2l_adc_isr()
* Renamed rzg2l_adc_parse_of() -> rzg2l_adc_parse_properties()
* Used devm_add_action_or_reset() for asserting the reset signals and
  disabling pm_runtime and eventually removing remove() callback
