[Linux-stm32] [PATCH 4/7] arm64: dts: st: add D1 domain for STM32MP25 family
Patrick Delaunay
patrick.delaunay at foss.st.com
Wed Nov 4 14:55:07 CET 2026
Add the D1 power domain for devices that require the Cortex-A35
cluster to remain in Run1. Keep S2Idle wake-up handling on the
EXTI1/RET_PD path.
