From 22c75545c41f38e6b4b85943e184e1999e3522f6 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 24 Nov 2017 17:27:49 +0100 Subject: [PATCH] ARM: dts: lpc18xx: Add generic compatible string for I2C EEPROM The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.
