Subject: [PATCH v4 0/3] Renesas RZ/G2L ADC driver support

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
* Added comments in isr handler for channel select interrupt
* Moved enabling/disabling of pclk during hw init in rzg2l_adc_hw_init()
* Dropped clock patch 3/4 (https://lore.kernel.org/patchwork/patch/1462152/)
  from previous series as its queued up in renesas-clk-for-v5.15

Changes for v2:
* Update binding doc, dropped gpios/renesas-rzg2l,adc-trigger-mode
  properties included channel property to represent each wired channel.
* Fixed review comments pointed by Alexandru, implemented pm runtime
  support, dropped mlock usage
* Fixed review comments pointed by Jonathan, renamed the macros,
  simplified the code.
* Included clock and DT patches
