-* Clock bindings for Freescale i.MX7 Dual
-
-Required properties:
-- compatible: Should be "fsl,imx7d-ccm"
-- reg: Address and length of the register set
-- #clock-cells: Should be <1>
-- clocks: list of clock specifiers, must contain an entry for each required
-  entry in clock-names
-- clock-names: should include entries "ckil", "osc"
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.  See include/dt-bindings/clock/imx7d-clock.h
-for the full list of i.MX7 Dual clock IDs.
