| The IEEE 1588 standard defines a method to precisely |
| synchronize distributed clocks over Ethernet networks. The |
| standard defines a Precision Time Protocol (PTP), which can |
| be used to achieve synchronization within a few dozen |
| microseconds. In addition, with the help of special hardware |
| time stamping units, it can be possible to achieve |
| synchronization to within a few hundred nanoseconds. |

| This driver adds support for PTP clocks as character |
| devices. If you want to use a PTP clock, then you should |
| also enable at least one clock driver as well. |
| |
| To compile this driver as a module, choose M here: the module |
| will be called ptp. |

| config PTP_1588_CLOCK_GIANFAR |
| tristate "Freescale eTSEC as PTP clock" |
| depends on PTP_1588_CLOCK |
| depends on GIANFAR |
| help |
| This driver adds support for using the eTSEC as a PTP |
| clock. This clock is only useful if your PTP programs are |
| getting hardware time stamps on the PTP Ethernet packets |
| using the SO_TIMESTAMPING API. |
| |
| To compile this driver as a module, choose M here: the module |
| will be called gianfar_ptp. |

| This driver adds support for using the IXP46X as a PTP |
| clock. This clock is only useful if your PTP programs are |
| getting hardware time stamps on the PTP Ethernet packets |
| using the SO_TIMESTAMPING API. |

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

| tristate "Intel PCH EG20T as PTP clock" |
| depends on PTP_1588_CLOCK |
| depends on PCH_GBE |
| help |
| This driver adds support for using the PCH EG20T as a PTP |
| clock. This clock is only useful if your PTP programs are |
| getting hardware time stamps on the PTP Ethernet packets |
| using the SO_TIMESTAMPING API. |
| |
| To compile this driver as a module, choose M here: the module |
| will be called ptp_pch. |
