13description: |
14  The RV1106 clock controller generates the clock and also implements a
15  reset controller for SoC peripherals.
16  (examples: provide SCLK_UART2\PCLK_UART2 and SRST_P_UART2\SRST_S_UART2 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/rv1106-cru.h headers and can be
20  used in device tree sources.
