+title: ROCKCHIP rk3568 Family Clock Control Module Binding

+description: |
+  The RK3568 clock controller generates the clock and also implements a
+  reset controller for SoC peripherals.
+  (examples: provide SCLK_UART1\PCLK_UART1 and SRST_P_UART1\SRST_S_UART1 for UART module)
+  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/rk3568-cru.h headers and can be
+  used in device tree sources.
