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. Changes for v3: - Re-sent.
