5   NXP S32 eMIOS PWM node for S32 SoCs. Each channel in eMIOS can be configured
10   For example to configuring eMIOS instance 0 with:
11     - Channel 0 for mode OPWFMB
12     - Channel 1 for mode OPWMB
13     - Channel 2 for mode OPWMCB with deadtime inserted at leading edge
14     - Channel 3 for mode SAIC, use internal timebase with input filter = 2 eMIOS clock
19         pwm-mode = "OPWFMB";
22         duty-cycle = <32768>;
28         master-bus = <&emios1_bus_a>;
29         pwm-mode = "OPWMB";
30         duty-cycle = <32768>;
31         phase-shift = <100>;
37         master-bus = <&emios1_bus_b>;
38         pwm-mode = "OPWMCB_LEAD_EDGE";
39         duty-cycle = <32768>;
40         dead-time = <100>;
46         pwm-mode = "SAIC";
48         input-filter = <2>;
53   phandle 'master-bus'. For OPWMB mode, PWM's period is master bus's period and
54   is 2 * master bus's period - 2 for OPWMCB mode. Please notice that the devicetree
56   'nxp,s32-emios' bindings.

91         A phandle to master-bus node that will be used as external timebase
97     pwm-mode:
102         - OPWFMB: provides waveforms with variable duty cycle and frequency,
105         - OPWMB:  generate pulses with programmable leading and trailing
111         - OPWMCB: generates a center aligned PWM with dead time insertion to the
