ptp: Added a clock driver for the National Semiconductor PHYTER.
This patch adds support for the PTP clock found on the DP83640. The basic clock operations and one external time stamp have been implemented. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: John Stultz <john.stultz@linaro.org>

65 Supports the DP83640 PHYTER with IEEE 1588 features.
66
67 This driver adds support for using the DP83640 as a PTP
68 clock. This clock is only useful if your PTP programs are
69 getting hardware time stamps on the PTP Ethernet packets
70 using the SO_TIMESTAMPING API.
71
72 In order for this to work, your MAC driver must also
73 implement the skb_tx_timetamp() function.
