[PATCH v2 04/11] ARM: dts: stm32: Add new pinmux groups for phyboard-sargas and phycore

From: Christophe Parant <hidden>
Date: 2025-07-09 15:10:21
Also in: linux-devicetree, lkml
Subsystem: arm/stm32 architecture, the rest · Maintainers: Maxime Coquelin, Alexandre Torgue, Linus Torvalds 

Add add alternate pinmux for following interfaces used on
phyBOARD-Sargas:
- UART4
- LTDC
- DCMI
- TIM5
- SAI2

Fix "ethernet0_rgmii_pins_d" pinmux used on phyCORE-STM32MP15x:
ETH_RGMII_GTX_CLK pin was missing.
