Where we used to treat each line as a channel, the PWM convention is to describe them as devices. The second documentation adaption entails adding support for PWM capture devices. A new clock is required as well as an IRQ line. We're also adding a new property similar to the one described above, but for capture channels. Typically, there will be less capture channels than PWM-out, since all channels have the latter capability, but only some have capture support.
