The RK3588 clock controller generates the clock and also implements a reset
|
||
|
controller for SoC peripherals. For example it provides SCLK_UART2 and
|
||
|
PCLK_UART2, as well as SRST_P_UART2 and SRST_S_UART2 for the second UART
|
||
|
module.
|
||
|
Each clock is assigned an identifier and client nodes can use this identifier
|
||
|
to specify the clock which they consume. All available clock and reset IDs
|
||
|
are defined as preprocessor macros in dt-binding headers.
