Subject: [v2, 0/7] Support programmable pins for Ocelot PTP driver
Date:   Tue, 31 Mar 2020 12:11:06 +0800

Precedence: bulk

The Ocelot PTP clock driver had been embedded into ocelot.c driver.
It had supported basic gettime64/settime64/adjtime/adjfine functions
by now which were used by both Ocelot switch and Felix switch.

This patch-set is to move current ptp clock code out of ocelot.c driver
maintaining as a single ocelot_ptp.c driver, and to implement 4
programmable pins with only PTP_PF_PEROUT function for now.
The PTP_PF_EXTTS function will be supported in the future, and it should
be implemented separately for Felix and Ocelot, because of different
hardware interrupt implementation in them.
---
Changes for v2:
	- Put PTP driver under drivers/net/ethernet/mscc/.
	- Dropped MAINTAINERS patch. Kept original maintaining.
	- Initialized PTP separately in ocelot/felix platforms.
	- Supported PPS case in programmable pin.
	- Supported disabling pin function since deadlock is fixed by Richard.
	- Returned -EBUSY if not finding pin available.
