[PATCH v13 0/5] Add RSCI driver for Renesas RZ/T2H SoC

[Prabhakar]

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

Hi all,

This patch series adds support for the Renesas RSCI (Renesas Serial
Communication Interface) driver for the RZ/T2H SoC. The RSCI is a serial
communication interface that provides UART functionality and is used in
various Renesas SoCs.

The series includes the following changes:
1. Device Tree Bindings
2. RSCI Driver Implementation
3. SH-SCI Driver Modifications
4. Maintainer Updates

v12->v13:
- Rebased on latest linux-next.
- Updated commit message for patch 1/5 to clarify the ABI change.
- Used `R9A09G077_CLK_PCLKM` macro for core clock.
- Dropped the defconfig patch as it is already in the queue.
- Added reviewed-by and acked-by tags to relevant patches.

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
