1 | * Clock bindings for Freescale i.MX31 | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: Should be "fsl,imx31-ccm" | ||
5 | - reg: Address and length of the register set | ||
6 | - interrupts: Should contain CCM interrupt | ||
7 | - #clock-cells: Should be <1> | ||
8 | |||
9 | The clock consumer should specify the desired clock by having the clock | ||
10 | ID in its "clocks" phandle cell. The following is a full list of i.MX31 | ||
11 | clocks and IDs. | ||
