title: Clock bindings for Freescale i.MX5

maintainers:

description: |
  The clock consumer should specify the desired clock by having the clock
  ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx5-clock.h
  for the full list of i.MX5 clock IDs.

properties:
  compatible:
    enum:
      - fsl,imx53-ccm
      - fsl,imx51-ccm
      - fsl,imx50-ccm

  reg:
    maxItems: 1

  interrupts:
    description: CCM provides 2 interrupt requests, request 1 is to generate
      interrupt for frequency or mux change, request 2 is to generate
      interrupt for oscillator read or PLL lock.
    items:
      - description: CCM interrupt request 1
