This patch series adds support for PTP event capture on the Aramda 80x0/70x0. This feature is mainly used by tools linux ts2phc(3) in order to synchronize a timestamping unit (like the mvpp2's TAI) and a system DPLL on the same PCB. The patch series includes 3 patches: the second one implements the actual extts function. Changes in v2: * Fixed a deadlock in the poll worker. * Removed tabs from comments. Changes in v3: * Added more explanation about the change in behavior in mvpp22_tai_start. * Explain the reason for choosing 95ms as a polling rate.
