[PATCH net-next 0/2] ptp: ptp_clockmatrix: Fix output 1 PPS alignment.

From: Vincent Cheng <redacted>

This series fixes a race condition that may result in the output clock
not aligned to internal 1 PPS clock.

Part of device initialization is to align the rising edge of output
clocks to the internal rising edge of the 1 PPS clock.  If the system
APLL and DPLL are not locked when this alignment occurs, the alignment
fails and a fixed offset between the internal 1 PPS clock and the
output clock occurs.

If a clock is dynamically enabled after power-up, the output clock
also needs to be aligned to the internal 1 PPS clock.

Vincent Cheng (2):
  ptp: ptp_clockmatrix: Add wait_for_sys_apll_dpll_lock.
  ptp: ptp_clockmatrix: Add alignment of 1 PPS to idtcm_perout_enable.
