| help |
| 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. |
