Changes since V4:
- add descriptions for interrupts and each item of it.

-* Clock bindings for Freescale i.MX6 Quad
-
-Required properties:
-- compatible: Should be "fsl,imx6q-ccm"
-- reg: Address and length of the register set
-- interrupts: Should contain CCM interrupt
-- #clock-cells: Should be <1>
-
-Optional properties:
-- fsl,pmic-stby-poweroff: Configure CCM to assert PMIC_STBY_REQ signal
- on power off.
- Use this property if the SoC should be powered off by external power
- management IC (PMIC) triggered via PMIC_STBY_REQ signal.
- Boards that are designed to initiate poweroff on PMIC_ON_REQ signal should
- be using "syscon-poweroff" driver instead.
-- clocks: list of clock specifiers, must contain an entry for each entry
- in clock-names
-- clock-names: valid names are "osc", "ckil", "ckih1", "anaclk1" and "anaclk2"
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx6qdl-clock.h
-for the full list of i.MX6 Quad and DualLite clock IDs.

-Examples:
-
-#include <dt-bindings/clock/imx6qdl-clock.h>

- reg = <0x020c4000 0x4000>;
- interrupts = <0 87 0x04 0 88 0x04>;
- #clock-cells = <1>;
-};
-
