[PATCH v2 2/7] dt-bindings: Amlogic: Document the CPU reset controller for Meson8b

[Carlo Caione]

From: Carlo Caione <carlo at endlessm.com>

The clock controller on Amlogic Meson8b SoCs has been extended with a
reset controller used to reset the CPU cores. It is used during SMP
bringup.

With this patch we extend the clock controller documentation.

 Each clock is assigned an identifier and client nodes can use this identifier
 to specify the clock which they consume. All available clocks are defined as
 preprocessor macros in the dt-bindings/clock/meson8b-clkc.h header and can be
 used in device tree sources.
+Similar identifiers exist for the CPU core reset lines.
 
 Example: Clock controller node:
 
 	clkc: clock-controller at c1104000 {
 		#clock-cells = <1>;
+		#reset-cells = <1>;
 		compatible = "amlogic,meson8b-clkc";
 		reg = <0xc1108000 0x4>, <0xc1104000 0x460>;
