Subject: [PATCH v2 03/14] arm64: dts: imx8mm-kontron: Disable pullups for I2C signals on OSM-S i.MX8MM
Date: Thu, 30 Nov 2023 17:16:03 +0100 [thread overview]
Message-ID: <20231130161657.556483-4-frieder@fris.de> (raw)
In-Reply-To: <20231130161657.556483-1-frieder@fris.de>
From: Frieder Schrempf <frieder.schrempf@kontron.de>
There are external pullup resistors on the board and due to silicon
errata ERR050080 let's disable the internal ones to prevent any
unwanted behavior in case they wear out.
Fixes: de9618e84f76 ("arm64: dts: Add support for Kontron SL/BL i.MX8MM OSM-S")
