From 566c2d83887f0570056833102adc5b88e681b0c7 Mon Sep 17 00:00:00 2001 From: Francesco Dolcini Date: Fri, 4 Oct 2024 17:24:19 +0200 Subject: [PATCH] net: fec: make PPS channel configurable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Depending on the SoC where the FEC is integrated into the PPS channel might be routed to different timer instances. Make this configurable from the devicetree. When the related DT property is not present fallback to the previous default and use channel 0.
