Subject: [v2, 0/7] Support programmable pins for Ocelot PTP driver
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.
