Re: [PATCH net v2 1/2] ptp: idt82p33: optimize idt82p33_adjtime

From: Min Li <redacted>

The current adjtime implementation is read-modify-write and immediately
triggered, which is not accurate due to slow i2c bus access. Therefore,
we will use internally generated 1 PPS pulse as trigger, which will
improve adjtime accuracy significantly. On the other hand, the new trigger
will not change TOD immediately but delay it to the next 1 PPS pulse.
