     13description: |
     14  The PX30 clock controller generates and supplies clocks to various
     15  controllers within the SoC and also implements a reset controller for SoC
     16  peripherals.
     17  Each clock is assigned an identifier and client nodes can use this identifier
     18  to specify the clock which they consume. All available clocks are defined as
     19  preprocessor macros in the dt-bindings/clock/px30-cru.h headers and can be
     20  used in device tree sources. Similar macros exist for the reset sources in
     21  these files.
     22  There are several clocks that are generated outside the SoC. It is expected
     23  that they are defined using standard clock bindings with following
     24  clock-output-names:
     25    - "xin24m"     - crystal input       - required
     26    - "xin32k"     - rtc clock           - optional
     27    - "i2sx_clkin" - external I2S clock  - optional
     28    - "gmac_clkin" - external GMAC clock - optional
