Patch 1 adds the new pin type to the DPLL netlink spec and UAPI header. Patch 2 adds a virtual NCO input pin to the zl3073x driver that allows userspace to switch a DPLL channel into NCO mode. The pin reports connected/active state when the channel is in NCO mode and handles the hardware-specific details of mode transitions including automatic df_offset capture and 1PPS phase preservation.
