Subject: [PATCH v4 0/3] Add pinctrl driver for RZ/T2H and RZ/N2H SoCs

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

Hi All,

Add pinctrl driver support for the Renesas RZ/T2H and RZ/N2H SoCs. The
RZ/T2H SoC supports 729 pins, while the RZ/N2H supports 576 pins. Both
share the same controller architecture, and the series includes
documentation, device tree bindings, and the driver implementation.

v3->v4:
- Used patternProperties for pin configuration nodes
- Expanded example nodes

v2->v3:
- Fixed Kconfig dependency
- Added dependency for 64bit to avoid build errors on 32bit systems
- Dropped refference to gpio.txt in the binding file
- Added missing include for bitfield.h in the driver

v1->v2:
- Added a new DT binding file
- Added support for RZ/N2H SoC

Cheers,
Prabhakar
