Subject: [PATCH 1/3] ARM: dts: armadillo800eva: Add I2C EEPROM for MAC address
Date: Thu,  9 Mar 2023 16:30:47 +0100	[thread overview]
Message-ID: <6d402b289fd20125d9f6f6b2a4f239aa1887daa6.1678375464.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1678375464.git.geert+renesas@glider.be>

Add a device node for the M24C01 I2C EEPROM which serves as external
storage for the Ethernet MAC address.

While at it, restore sort order (by unit address) of the I2C devices.
