+description: |
+  The RK3399 clock controller generates and supplies clock 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/rk3399-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,
+    - "clkin_gmac" - external GMAC clock - optional,
+    - "clkin_i2s" - external I2S clock - optional,
+    - "pclkin_cif" - external ISP clock - optional,
+    - "clk_usbphy0_480m" - output clock of the pll in the usbphy0
+    - "clk_usbphy1_480m" - output clock of the pll in the usbphy1
