From 5293e8f2a854344ef9aba2391b44c7a437889ebb Mon Sep 17 00:00:00 2001 From: Lad Prabhakar Date: Fri, 8 Aug 2025 14:30:15 +0100 Subject: dt-bindings: pinctrl: renesas: Document RZ/T2H and RZ/N2H SoCs Document the pin and GPIO controller IP for the Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs, and add the shared DTSI header file used by both the bindings and the driver. The RZ/T2H SoC supports 729 pins, while RZ/N2H supports 576 pins. Both share the same controller architecture; separate compatible strings are added for each SoC to distinguish them.
