If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 6562d6e350284307e33ea10c7f46a6661ff22770 Mon Sep 17 00:00:00 2001 From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx> Date: Fri, 15 Oct 2021 14:48:38 +0200 Subject: arm64: dts: imx8mm-kontron: Fix polarity of reg_rst_eth2 From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx> commit 6562d6e350284307e33ea10c7f46a6661ff22770 upstream. The regulator reg_rst_eth2 should keep the reset signal of the USB ethernet adapter deasserted anytime. Fix the polarity and mark it as always-on. Anyway, using the regulator is only a workaround for the missing support of specifying a reset GPIO for USB devices in a generic way. As we don't have a solution for this at the moment, at least fix the current workaround.
