+title: Rockchip RK3528 Clock and Reset Controller
+
+maintainers:
+ - Yao Zi <ziyao@disroot.org>
+
+description: |
+ The RK3528 clock controller generates the clock and also implements a reset
+ controller for SoC peripherals. For example, it provides SCLK_UART0 and
+ PCLK_UART0 as well as SRST_P_UART0 and SRST_S_UART0 for the first UART
+ module.
+ Each clock is assigned an identifier, consumer nodes can use it to specify
+ the clock. All available clock and reset IDs are defined in dt-binding
+ headers.
