ptp_pch: Restore dependency on PCI

2021-08-26T12:36:17Z

[ Upstream commit 55c8fca1dae1fb0d11deaa21b65a647dedb1bc50 ] During the swap dependency on PCH_GBE to selection PTP_1588_CLOCK_PCH incidentally dropped the implicit dependency on the PCI. Restore it.

ptp: add QorIQ PTP support for DPAA2

2019-06-15T20:43:06Z

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. Signed-off-by: Yangbo Lu Signed-off-by: David S.

ptp: add QorIQ PTP support for ENETC

2019-02-12T17:58:48Z

This patch is to add QorIQ PTP support for ENETC. ENETC PTP driver which is a PCI driver for same 1588 timer IP block will reuse QorIQ PTP driver. Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

ptp: add debugfs support for ptp_qoriq

2019-01-23T04:21:57Z

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. echo 1 > /sys/kernel/debug/2d10e00.ptp_clock/fiper1-loopback Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

ptp: support DPAA FMan 1588 timer in ptp_qoriq

2018-06-26T13:15:14Z

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

2018-05-29T03:05:11Z

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. Signed-off-by: Yangbo Lu Acked-by: Richard Cochran Signed-off-by: David S. Miller

PTP: add kvm PTP driver

2017-02-08T16:16:20Z

Add a driver with gettime method returning hosts realtime clock. This allows Chrony to synchronize host and guest clocks with high precision (see results below). chronyc> sources MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== To configure Chronyd to use PHC refclock, add the following line to its configuration file: refclock PHC /dev/ptpX poll 3 dpoll -2 offset 0 Where /dev/ptpX is the kvmclock PTP clock.
