Hi,

Series adds support for IA55 available on RZ/G3S SoC.
Patches are split as follows:
- 1/9 adds IA55 clock
- 2-4/9 minor cleanups to align with the suggestions at [1] and
  coding style recommendations
- 5/9 implement restriction described in HW manual for ISCR register
- 6/9 add a macro to retrieve TITSR base address based on it's index
- 7/9 add suspend to RAM support
- 8/9 updates documentation
- 9/9 adds IA55 device tree node

Thank you,
Claudiu Beznea

Changes in v3:
- kept driver private data object as pointer
- moved patch 1/9 from v2 (dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/G3S)
  after IRQ controller driver feature patches

Changes in v2:
- collected Conor's tag
- updated commit description according to code review comments
- added patches 4, 5 according to review recommendations
- updated patch 7/9 to retrieve only TITSR base address; dropped the rest
  of the changes for the moment
- in patch 8/9 use local variable in suspend/resume functions for controller's
  base address, indent initialized structures members to tabs, updated
  private driver data structure name
- patch 3/7 from v1 was replaced by patch 7/9 in v2
- patch 5/7 from v1 was renamed "Add support for suspend to RAM"
- cleanup patches were kept at the beginning of the series and features at the end
