[PATCH 01/12] dt-bindings: power: reset: Document ti,sci-reboot compatible

[Andrew Davis]

This calls into the system firmware using TI-SCI to reboot the system.
Used as a fallback when PSCI is unable or not available to reboot
the system.

+title: TI-SCI reboot controller
+

+  - Andrew Davis <afd at ti.com>
+
+description: |
+  Some TI SoCs contain a system controller (like the Power Management Micro
+  Controller (PMMC) on Keystone 66AK2G SoC) that are responsible for controlling
+  the state of the various hardware modules present on the SoC. Communication
+  between the host processor running an OS and the system controller happens
+  through a protocol called TI System Control Interface (TI-SCI protocol).
+
+  This reboot controller node uses the TI SCI protocol to perform a device reboot.
+
+  Must be a child node of the associated TI-SCI system controller node.
