Message-Id: <20190121104143.46782-1-yangbo.lu@nxp.com> Date: Mon, 21 Jan 2019 18:41:37 +0800 From: Yangbo Lu <yangbo.lu@....com> To: netdev@...r.kernel.org, devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: "David S . Miller" <davem@...emloft.net>, Richard Cochran <richardcochran@...il.com>, Rob Herring <robh+dt@...nel.org>, Shawn Guo <shawnguo@...nel.org>, Yangbo Lu <yangbo.lu@....com> Subject: [v3, 0/6] External trigger stamp fifo support for ptp_qoriq 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.
