Subject: [PATCH v12 0/7] Add support for RSCI driver

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series adds support for Renesas RSCI driver for RZ/N2H and
RZ/T2H SoCs.

Note
- This patch series is split up from the series [1] to make it
  easier to review and test.
- patch 03/12 was sent out individually [2] and is now merged
  into the series for convenience.

[2] https://lore.kernel.org/all/20250609192344.293317-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

v11->v12:
- Rebased on latest linux-next.
- Added defconfig patch to enable RSCI driver.
- Added RZ/N2H support to the dt-bindings
- Used port ops callbacks in sci_shutdown() to allow RSCI driver
  to reuse the core shutdown logic.
- Added reviewed-by tags.

v10->v11:
- Rebased on latest linux-next.
- Added a new patch to update the dt-bindings maintainer entry.
- Added a new patch to use port ops callbacks.
- Implemented shutdown_complete callback
- Added reviewed-by tags.

Cheers,
Prabhakar
