[PATCH v14 09/10] arm64: dts: qcom: qcs6490-rb3gen2: Add PSCI SYSTEM_RESET2 types

From: Shivendra Pratap
Date: Fri Aug 15 2025 - 10:39:15 EST


From: Elliot Berman <elliot.berman@xxxxxxxxxxxxxxxx>

Add support for SYSTEM_RESET2 vendor-specific resets in
qcs6490-rb3gen2 as reboot-modes. 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.
