From 89bd68a7484880900b47bcadd1b5671c52592d16 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Wed, 23 Jun 2021 16:13:35 +0300 Subject: [PATCH] ARM: dts: at91: fix the GPIO polarity for onewire The GPIO polarity for onewire must be GPIO_ACTIVE_HIGH. On previous versions this used to work as it looks like the right flag values are being passed since : https://lists.denx.de/pipermail/u-boot/2020-April/407195.html And that series broke the old functionality for onewire nodes. Some boards had the correct value for the polarity, but it wasn't clear so I replaced it with the right macro for the flag, instead of an empty value.
