13description: |
14 The RK3568 clock controller generates the clock and also implements a
15 reset controller for SoC peripherals.
16 (examples: provide SCLK_UART1\PCLK_UART1 and SRST_P_UART1\SRST_S_UART1 for UART module)
17 Each clock is assigned an identifier and client nodes can use this identifier
18 to specify the clock which they consume. All available clocks are defined as
19 preprocessor macros in the dt-bindings/clock/rk3568-cru.h headers and can be
20 used in device tree sources.
