From 1aa772be0444a2bd06957f6d31865e80e6ae4244 Mon Sep 17 00:00:00 2001 From: Francesco Dolcini Date: Fri, 4 Oct 2024 17:24:17 +0200 Subject: [PATCH] dt-bindings: net: fec: add pps channel property Add fsl,pps-channel property to select where to connect the PPS signal. This depends on the internal SoC routing and on the board, for example on the i.MX8 SoC it can be connected to an external pin (using channel 1) or to internal eDMA as DMA request (channel 0).
