Subject: [PATCH 1/9] dt-bindings: clock: add mtmips SoCs system controller
Adds device tree binding documentation for system controller node present
in Mediatek MIPS and Ralink SOCs. This node is a clock and reset provider
for the rest of the world. This covers RT2880, RT3050, RT3052, RT3350,
RT3883, RT5350, MT7620, MT7628 and MT7688 SoCs.

+description: |
+ MediaTek MIPS and Ralink SoCs provides a system controller to allow
+ to access to system control registers. These registers include clock
+ and reset related ones so this node is both clock and reset provider
+ for the rest of the world.
+
+ These SoCs have an XTAL from where the cpu clock is
+ provided as well as derived clocks for the bus and the peripherals.
