* Clock bindings for Freescale i.MX25
|
|
|
|
Required properties:
|
|
- compatible: Should be "fsl,imx25-ccm"
|
|
- reg: Address and length of the register set
|
|
- interrupts: Should contain CCM interrupt
|
|
- #clock-cells: Should be <1>
|
|
|
|
The clock consumer should specify the desired clock by having the clock
|
|
ID in its "clocks" phandle cell. The following is a full list of i.MX25
|
|
clocks and IDs.
