So . . . yeah. For 4.x kernels it's broken.
william@beaglebone:~$ ls /sys/class/pwm/
william@beaglebone:~$ nano bspwm_P9_22_13-00A0.dts
william@beaglebone:~$ dtc -O dtb -o bspwm_P9_22_13-00A0.dtbo -b 0 -@
bspwm_P9_22_13-00A0.dts
Error: bspwm_P9_22_13-00A0.dts:53.2-54.1 syntax error
FATAL ERROR: Unable to parse input tree
At minimum and just at a glance.
fragment@20 {
target = <&epwmss0>;
__overlay__ {
status = "okay";
};
};
fragment@21 {
target = <&ehrpwm0>;
__overlay__ {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <>;
};
};
Fragment @20 here is from a working overlay file. epwmss* is required to
use ehrpwm* modules in kernel 4.x. Additionally . . . there's a syntax
error that I do not care to look into . . .
