[PATCH RESEND v3 2/4] dt-bindings: raspberrypi,bcm2835-firmware: Include 'reboot-mode.yaml'

[Gregor Herburger <gregor.herburger@linutronix.de>]

The Raspberry Pi firmware allows to set a reboot mode called tryboot
that allows to try booting from a different partition to allow updating
of the boot partition. Allow reboot mode properties by referencing the
reboot-mode schema. The firmware allows a 32bit value to be sent as
reboot flag so restrict the maxItems to 1.
