Yangbo Lu 10bc877c76 ptp_qoriq: check valid status before reading extts fifo ... For PTP timer supporting external trigger timestamp FIFO, there is a valid bit in TMR_STAT register indicating the timestamp is available. For PTP timer without FIFO, there is not TMR_STAT register. This patch is to check the valid bit for the FIFO before reading timestamp, and to avoid operating TMR_STAT register for PTP timer without the FIFO.
