From 8df0eba814f666e92056909f59fd70b8e0af812d Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Wed, 13 Aug 2025 16:07:41 +0200 Subject: [PATCH] arm64: dts: rockchip: force PMIC reset behavior to restart PMU on RK3588 Jaguar The bootloader for RK3588 Jaguar currently forces the PMIC reset behavior (stored in RST_FUN bitfield in register SYS_CFG3 of the PMIC) to 0b1X which is incorrect for our devices. It is required to restart the PMU as otherwise the companion microcontroller cannot detect the PMIC (and by extension the full product and main SoC) being rebooted which is an issue as that is used to reset a few things like the PWM beeper and watchdogs. Let's add the new rockchip,reset-mode property to make sure the PMIC reset behavior is the expected one.
