ptp: ixp46x: move adjacent to ethernet driver

2020-01-12T20:59:52+00:00

The ixp46x ptp driver has a somewhat unusual setup, where the ptp
driver and the ethernet driver are in different directories but
access the same registers that are defined a platform specific
header file.

Moving everything into drivers/net/ makes it look more like most
other ptp drivers and allows compile-testing this driver on
other targets.

ptp: Add a driver for InES time stamping IP core.

2019-12-26T03:51:34+00:00

The InES at the ZHAW offers a PTP time stamping IP core.  The FPGA
logic recognizes and time stamps PTP frames on the MII bus.  This
patch adds a driver for the core along with a device tree binding to
allow hooking the driver to MII buses.

ptp: clockmatrix: add I2C dependency

ptp: ptp_clockmatrix: Fix build error

ptp: Add a ptp clock driver for IDT ClockMatrix.

2019-11-04T01:35:40+00:00

The IDT ClockMatrix (TM) family includes integrated devices that provide
eight PLL channels.  Each PLL channel can be independently configured as a
frequency synthesizer, jitter attenuator, digitally controlled
oscillator (DCO), or a digital phase lock loop (DPLL).  Typically
these devices are used as timing references and clock sources for PTP
applications.  This patch adds support for the device.

ptp: add QorIQ PTP support for DPAA2

2019-06-15T20:43:06+00:00

This patch is to add QorIQ PTP support for DPAA2.
Although dpaa2-ptp.c driver is a fsl_mc_driver which
is using MC APIs for register accessing, it's same
IP block with eTSEC/DPAA/ENETC 1588 timer. We will
convert to reuse ptp_qoriq driver by using register
ioremap and dropping related MC APIs.
Also allow to compile ptp_qoriq with COMPILE_TEST.

ptp: add debugfs support for ptp_qoriq

2019-01-23T04:21:57+00:00

This patch is to add debugfs support for ptp_qoriq. Current debugfs
supports to control fiper1/fiper2 loopback mode. If the loopback mode
is enabled, the fiper1/fiper2 pulse is looped back into trigger1/
trigger2 input. This is very useful for validating hardware and driver
without external hardware. Below is an example to enable fiper1 loopback.
