+description: |
+  The RV1108 clock controller generates and supplies clocks to various
+  controllers within the SoC and also implements a reset controller for SoC
+  peripherals.
+  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/rv1108-cru.h headers and can be
+  used in device tree sources. Similar macros exist for the reset sources in
+  these files.
+  There are several clocks that are generated outside the SoC. It is expected
+  that they are defined using standard clock bindings with following
+  clock-output-names:
+    - "xin24m"   - crystal input                              - required
+    - "ext_vip"  - external VIP clock                         - optional
+    - "ext_i2s"  - external I2S clock                         - optional
+    - "ext_gmac" - external GMAC clock                        - optional
+    - "hdmiphy"  - external clock input derived from HDMI PHY - optional
+    - "usbphy"   - external clock input derived from USB PHY  - optional
