+What:		/sys/class/reboot-mode/<driver>/reboot_modes
+Date:		August 2025
+KernelVersion:	6.17.0-rc1
+Contact:	linux-pm@vger.kernel.org
+		Description:
+		This interface exposes the reboot-mode arguments
+		registered with the reboot-mode framework. It is
+		a read-only interface and provides a space
+		separated list of reboot-mode arguments supported
+		on the current platform.
+		Example:
+		 recovery fastboot bootloader
+
+		The exact sysfs path may vary depending on the
+		name of the driver that registers the arguments.
+		Example:
+		 /sys/class/reboot-mode/nvmem-reboot-mode/reboot_modes
+		 /sys/class/reboot-mode/syscon-reboot-mode/reboot_modes
+		 /sys/class/reboot-mode/qcom-pon/reboot_modes
+
+		The supported arguments can be used by userspace
+		to invoke device reset using the reboot() system
+		call, with the "argument" as string to "*arg"
+		parameter along with LINUX_REBOOT_CMD_RESTART2.
+		Example:
+		 reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2,
+		        LINUX_REBOOT_CMD_RESTART2, "bootloader");
+
+		A driver can expose the supported arguments by
+		registering them with the reboot-mode framework
+		using the property names that follow the
+		mode-<argument> format.
+		Example:
+		 mode-bootloader, mode-recovery.
+
+		This attribute is useful for scripts or initramfs
+		logic that need to programmatically determine
+		which reboot-mode arguments are valid before
+		triggering a reboot.
