Subject: [PATCH v3 04/14] arm64: dts: imx8mm-kontron: Disable pullups for I2C signals on SL/BL i.MX8MM
Date: Wed,  6 Dec 2023 15:41:07 +0100	[thread overview]
Message-ID: <20231206144201.46911-5-frieder@fris.de> (raw)
In-Reply-To: <20231206144201.46911-1-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: 8668d8b2e67f ("arm64: dts: Add the Kontron i.MX8M Mini SoMs and baseboards")
