+config PTP_1588_CLOCK
+	tristate "PTP clock support"
+	depends on NET && POSIX_TIMERS
+	default ETHERNET
+	select PPS
+	select NET_PTP_CLASSIFY
+	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.
+
+config PTP_1588_CLOCK_OPTIONAL
+	tristate
+	default y if PTP_1588_CLOCK=n
+	default PTP_1588_CLOCK
+	help
+	  Drivers that can optionally use the PTP_1588_CLOCK framework
+	  should depend on this symbol to prevent them from being built
+	  into vmlinux while the PTP support itself is in a loadable
+	  module.
+	  If PTP support is disabled, this dependency will still be
+	  met, and drivers refer to dummy helpers.

+	default y
+	help
+	  This driver adds support for using the Digital timing engine
+	  (DTE) in the Broadcom SoC's as a PTP clock.
+
+	  The clock can be used in both wired and wireless networks
+	  for PTP purposes.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called ptp_dte.

+	depends on PTP_1588_CLOCK
+	default y
+	help
+	  This driver adds support for using the Freescale QorIQ 1588
+	  timer 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-qoriq.

+	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_timestamp() function.

+	depends on PTP_1588_CLOCK
+	help
+	  This driver adds support for using the ZHAW InES 1588 IP
+	  core.  This clock is only useful if the MII bus of your MAC
+	  is wired up to the core.

+	depends on NET
+	depends on PTP_1588_CLOCK
+	help
+	  This driver adds support for using the PCH EG20T as a PTP
+	  clock. The hardware supports time stamping of PTP packets
+	  when using the end-to-end delay (E2E) mechanism. The peer
+	  delay mechanism (P2P) is not supported.
+
+	  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.

+	  This driver adds support for using kvm infrastructure as a PTP
+	  clock. This clock is only useful if you are using KVM guests.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called ptp_kvm.
