-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.yaml 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@...50000 {
- 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>;
-};
