[v3,0/6] External trigger stamp fifo support for ptp_qoriq

Message

Yangbo Lu Jan. 21, 2019, 10:41 a.m. UTC

This patch-set is to add external trigger stamp fifo support by a new
binding "fsl,extts-fifo", and to add fiper pulse loopback support which
is very useful for validating trigger without external hardware.
Also fixed issues in interrupt enabling/handling.

"fsl,extts-fifo" is required to be added into 1588 timer dts node whose
hardware supports it. The work will be done for some QorIQ platforms dts in
the near future.

Yangbo Lu (6):
  ptp_qoriq: fix interrupt enabling and handling
  ptp_qoriq: support external trigger stamp FIFO
  dt-binding: ptp_qoriq: document "fsl,extts-fifo" property
  ARM: dts: ls1021a: add 1588 external trigger stamp fifo support
  ptp: add debugfs support for ptp_qoriq
  MAINTAINERS: add drivers/ptp/ptp_qoriq_debugfs.c into QorIQ PTP list
