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

21 | This driver adds support for PTP clocks as character | |
22 | devices. If you want to use a PTP clock, then you should | |
23 | also enable at least one clock driver as well. | |
24 | ||
25 | To compile this driver as a module, choose M here: the module | |
26 | will be called ptp. | |

35 | This driver adds support for using the Digital timing engine | |
36 | (DTE) in the Broadcom SoC's as a PTP clock. | |

38 | The clock can be used in both wired and wireless networks | |
39 | for PTP purposes. | |
