* Clock bindings for Freescale i.MX6 SLL
Required properties:
- compatible: Should be "fsl,imx6sll-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", "ipp_di0" and "ipp_di1"
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx6sll-clock.h
for the full list of i.MX6 SLL clock IDs.
Examples:
#include <dt-bindings/clock/imx6sll-clock.h>
clks: clock-controller@20c4000 {
compatible = "fsl,imx6sll-ccm";
reg = <0x020c4000 0x4000>;
interrupts = <GIC_SPI 87 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 88 IRQ_TYPE_LEVEL_HIGH>;
#clock-cells = <1>;
clocks = <&ckil>, <&osc>, <&ipp_di0>, <&ipp_di1>;
clock-names = "ckil", "osc", "ipp_di0", "ipp_di1";
};
uart1: serial@2020000 {
compatible = "fsl,imx6sl-uart", "fsl,imx6q-uart", "fsl,imx21-uart";
reg = <0x02020000 0x4000>;
interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6SLL_CLK_UART1_IPG>,
<&clks IMX6SLL_CLK_UART1_SERIAL>;
clock-names = "ipg", "per";
};
Device Tree Clock bindings for Intel's SoCFPGA Stratix10 platform
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible : shall be
"intel,stratix10-clkmgr"
- reg : shall be the control register offset from CLOCK_MANAGER's base for the clock.
- #clock-cells : from common clock binding, shall be set to 1.
Example:
clkmgr: clock-controller@ffd10000 {
compatible = "intel,stratix10-clkmgr";
reg = <0xffd10000 0x1000>;
#clock-cells = <1>;
