|
|
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.
