From fa36b8209ba600828646287ad14e527074b48247 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Tue, 10 Jun 2025 17:23:07 +0200 Subject: [PATCH] ARM: dts: stm32: Add pinmux for CM4 leds pins The GPIO H7 on boards stm32mp15xx-dkx and the GPIO D8 on boards stm32mp15xx-ed1 are used by the coprocessor Cortex-M4. Linux running on Cortex-A should not use the GPIO and should left it available for the coprocessor. Add two pinmux groups, one for each families of boards, setting the GPIO function as Reserved (RSVD).
