ptp: clockmatrix: add I2C dependency

2019-12-13T23:42:09+00:00

Without I2C, we get a link failure:

ptp: ptp_clockmatrix: Fix build error

2019-11-12T20:12:39+00:00

When do randbuilding, we got this warning:

WARNING: unmet direct dependencies detected for PTP_1588_CLOCK
  Depends on [n]: NET [=y] && POSIX_TIMERS [=n]
  Selected by [y]:

Make PTP_1588_CLOCK_IDTCM depends on PTP_1588_CLOCK to fix this.

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.

ptp: support DPAA FMan 1588 timer in ptp_qoriq

2018-06-26T13:15:14+00:00

This patch is to support DPAA (Data Path Acceleration Architecture)
1588 timer by adding "fsl,fman-ptp-timer" compatible, sharing
interrupt with FMan, adding FSL_DPAA_ETH dependency, and fixing
up register offset.

ptp: rework gianfar_ptp as QorIQ common PTP driver

2018-05-29T03:05:11+00:00

gianfar_ptp was the PTP clock driver for 1588 timer
module of Freescale QorIQ eTSEC (Enhanced Three-Speed
Ethernet Controllers) platforms. Actually QorIQ DPAA
(Data Path Acceleration Architecture) platforms is
also using the same 1588 timer module in hardware.

This patch is to rework gianfar_ptp as QorIQ common
PTP driver to support both DPAA and eTSEC. Moved
gianfar_ptp.c to drivers/ptp/, renamed it as
ptp_qoriq.c, and renamed many variables. There were
not any function changes.
