Subject: [PATCH] arm64: dts: imx8mn-evk: Pass GPIO_OPEN_DRAIN flag
Date: Wed, 21 Jun 2023 14:37:11 -0300 [thread overview]
Message-ID: <20230621173711.1063946-1-festevam@gmail.com> (raw)
From: Fabio Estevam <festevam@denx.de>
scl-gpios and sda-gpios need GPIO_OPEN_DRAIN flag, otherwise the
following run-time warning is seen:
gpio-144 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file
gpio-146 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file
