Subject: [PATCH 0/2] Add support for configuring pin properties on RZ/T2H-N2H SoCs

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

Hi all,

This patch series adds support for configuring pin properties on the
Renesas RZ/T2H-N2H SoCs. The RZ/T2H allows configuring pin properties
through the DRCTLm (I/O Buffer Function Switching) registers, including:
- Drive strength (low/middle/high/ultra high)
- Pull-up/pull-down/no-bias configuration (3 options: no pull, pull-up,
  pull-down)
- Schmitt trigger control (enable/disable)
- Slew rate control (2 options: slow/fast)

Cheers,
Prabhakar
