Repair the docs build warnings in this file by unindenting the description,
adding blank lines, and using `` to quote *arg.

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 standard reboot() system
|
|
call interface, with the "argument" as string to ``*arg``
|
|
parameter along with ``LINUX_REBOOT_CMD_RESTART2``.
|
|
|
|
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.
