* Clock bindings for Freescale i.MX21
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,imx21-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. See include/dt-bindings/clock/imx21-clock.h
|
|
for the full list of i.MX21 clock IDs.
|
|
|
|
Examples:
|
|
clks: ccm@10027000{
|
|
compatible = "fsl,imx21-ccm";
|
|
reg = <0x10027000 0x800>;
|
|
#clock-cells = <1>;
|
|
};
|
|
|
|
uart1: serial@1000a000 {
|
|
compatible = "fsl,imx21-uart";
|
|
reg = <0x1000a000 0x1000>;
|
|
interrupts = <20>;
|
|
clocks = <&clks IMX21_CLK_UART1_IPG_GATE>,
|
|
<&clks IMX21_CLK_PER1>;
|
|
clock-names = "ipg", "per";
|
|
status = "disabled";
|
|
};
