Looks fine to me. I'll assume you reiterate the series for patch #2 and
so I will mark this patch as deferred in patchwork.

+
+description:
+  The OpenCores PTC ip core contains a PWM controller. When operating in PWM
+  mode, the PTC core generates binary signal with user-programmable low and
+  high periods. All PTC counters and registers are 32-bit.
