Subject: [PATCH 5/5] ARM: dts: at91: at91-sama5d27_som1: Enable eeprom device
Date: Fri, 3 Apr 2020 06:12:27 +0000	[thread overview]
Message-ID: <20200403061222.1277147-5-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20200403061222.1277147-1-tudor.ambarus@microchip.com>

From: Ludovic Desroches <ludovic.desroches@microchip.com>

There is an EEPROM on at91-sama5d27_som1 connected to i2c0. i2c0 node
has to be moved from at91-sama5d27_som1_ek to at91-sama5d27_som1.

Enable the i2c EEPROM found on at91-sama5d27_som1. Add an alias for the
i2c node.
