+description: |
+  The RK3588 clock controller generates the clock and also implements a
+  reset controller for SoC peripherals.
+  (examples: provide SCLK_UART2\PCLK_UART2 and SRST_P_UART2\SRST_S_UART2 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/rk3588-cru.h headers and can be
+  used in device tree sources.
