Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc-next
Ben Hutchings says:
====================
1. Extension to PPS/PTP to allow for PHC devices where pulses are
subject to a variable but measurable delay.
2. PPS/PTP/PHC support for Solarflare boards with a timestamping
peripheral.
3. MTD support for updating the timestamping peripheral on those boards.
4. Fix for potential over-length requests to firmware.
====================
