Subject: [PATCH v3 4/4] arm64: dts: qcom: Add PSCI SYSTEM_RESET2 types for qcm6490-idp
Date: Wed, 15 May 2024 16:09:47 -0700 [thread overview]
Message-ID: <20240515-arm-psci-system_reset2-vendor-reboots-v3-4-16dd4f9c0ab4@quicinc.com> (raw)
In-Reply-To: <20240515-arm-psci-system_reset2-vendor-reboots-v3-0-16dd4f9c0ab4@quicinc.com>
Add nodes for the vendor-defined system 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.
