I'm pretty confused about how to read the address of beaglebone black's pins. From the datasheet I got, the address starting from 44e10000, and offset from 44e10800. However, when I deployed a device tree overlay and enabled the epwmss2, epwmss1, ehrpwm2, ehrpwm1, I got from /sys/devices/platform/ocp/ the following virtual file systems 48302000.epwmss, 48304000.epwmss. And under each folder, I got access to a pair of eqep and pwm. Also, under /sys/class/pwm, I also got pwmchip0 and pwmchip2. So, I'm confused about how should I match which is which?
