Freescale i.MX TPM PWM controller
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,imx7ulp-pwm".
|
|
- reg: Physical base address and length of the controller's registers.
|
|
- #pwm-cells: Should be 3. See pwm.txt in this directory for a description of the cells format.
|
|
- clocks : The clock provided by the SoC to drive the PWM.
|
|
- interrupts: The interrupt for the PWM controller.
|
|
|
|
Note: The TPM counter and period counter are shared between multiple channels, so all channels
|
|
should use same period setting.
|
|
|
|
Example:
|
|
|
|
tpm4: pwm@40250000 {
|
|
compatible = "fsl,imx7ulp-pwm";
|
|
reg = <0x40250000 0x1000>;
|
|
assigned-clocks = <&pcc2 IMX7ULP_CLK_LPTPM4>;
|
|
assigned-clock-parents = <&scg1 IMX7ULP_CLK_SOSC_BUS_CLK>;
|
|
clocks = <&pcc2 IMX7ULP_CLK_LPTPM4>;
|
|
#pwm-cells = <3>;
|
|
};
