[PATCH v2 0/2] ARM: BCM63xx: reboot support

[Florian Fainelli]

Hi all,

This patch series allows the use of the generic "syscon-reboot" driver for
Broadcom's BCM63xx ARM-based SoCs.

Let me know your thoughts on this so I can submit these in a future Broadcom
SoC pull request, thanks!

Changes in v2:

- dropped the custom driver and use "syscon-reboot"

Florian Fainelli (2):
  dt-bindings: Add documentation for the BCM63138 timer and
    syscon-reboot
  ARM: dts: BCM63xx: Add timer and syscon-reboot nodes

[PATCH v2 1/2] dt-bindings: Add documentation for the BCM63138 timer and syscon-reboot

[Florian Fainelli]

A timer node and a syscon-reboot node are required for software reboot
to work on BCM63138, document these two nodes in the platform binding.

[PATCH v2 2/2] ARM: dts: BCM63xx: Add timer and syscon-reboot nodes

[Florian Fainelli]

Add a "brcm,bcm6328-timer" and "syscon-reboot" nodes to allow the
generic syscon-reboot driver to reset a BCM63138 SoC.
