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.
+Similarly a preprocessor macro for each reset line is defined in
+dt-bindings/reset/amlogic,meson8b-clkc-reset.h (which can be used from the
+device tree sources).

clkc: clock-controller@c1104000 {

reg = <0xc1108000 0x4>, <0xc1104000 0x460>;
