+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.
