Subject: [PATCH v3 1/2] arm64: dts: qcom: hamoa: Add PSCI SYSTEM_RESET2 types
Date: Tue, 1 Sep 2026 00:55:45 -0700 [thread overview]
Message-ID: <20260901075552.3558150-2-xin.liu@oss.qualcomm.com> (raw)
In-Reply-To: <20260901075552.3558150-1-xin.liu@oss.qualcomm.com>
Add support for SYSTEM_RESET2 vendor-specific resets as
reboot-modes in the psci node. Describe the resets: "bootloader"
will cause device to reboot and stop in the bootloader's fastboot
mode. "edl" will cause device to reboot into "emergency download
mode", which permits loading images via the Firehose protocol.
