From 54347344ce47005848333f953f401cd0c6f691f3 Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Wed, 29 Sep 2021 15:04:18 -0700 Subject: [PATCH] imx: ventana: remove phy gpio reset from dt We configure network phy configuration for internal delay, LED config, and clock config. If we leave the phy reset gpio defined in dt the kernel may issue a reset to the phy and break these configs. While some may be handled by a kernel phy driver, others may not (typically LED config).
