1 TI SOC EHRPWM based PWM controller
4 - compatible: Must be "ti,<soc>-ehrpwm".
5 for am33xx - compatible = "ti,am33xx-ehrpwm";
6 for da850 - compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
7 - #pwm-cells: Should be 3. Number of cells being used to specify PWM property.
8 First cell specifies the per-chip index of the PWM to use, the second
9 cell is the period in nanoseconds and bit 0 in the third cell is used to
10 encode the polarity of PWM output. Set bit 0 of the third in PWM specifier
11 to 1 for inverse polarity & set to 0 for normal polarity.
12 - reg: physical base address and size of the registers map.
15 - ti,hwmods: Name of the hwmod associated to the EHRPWM:
16 "ehrpwm<x>", <x> being the 0-based instance number from the HW spec
20 ehrpwm0: ehrpwm@0 { /* EHRPWM on am33xx */
21 compatible = "ti,am33xx-ehrpwm";
23 reg = <0x48300200 0x100>;
24 ti,hwmods = "ehrpwm0";
27 ehrpwm0: ehrpwm@0 { /* EHRPWM on da850 */
28 compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
30 reg = <0x300000 0x2000>;
