Subject: [PATCH] arm64: dts: debix-a: Remove i2c2 from base .dts
Date: Tue, 26 Mar 2024 00:50:48 +0200	[thread overview]
Message-ID: <20240325225048.1159-1-laurent.pinchart@ideasonboard.com> (raw)

From: Jacopo Mondi <jacopo@jmondi.org>

The I2C2 bus is used for the CSI and DSI connectors only, no devices are
connected to it on neither the Debix Model A nor its IO board. Remove
the bus from the board's .dts and rely on display panel or camera sensor
overlsy to enable it when necessary.
