+description: |
+  The PX30 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/px30-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
+    - "xin32k"     - rtc clock           - optional
+    - "i2sx_clkin" - external I2S clock  - optional
+    - "gmac_clkin" - external GMAC clock - optional
