From fd393188064e3d01a91a21160751f60ff5ce5def Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 15 Jun 2017 20:54:14 +0200 Subject: [PATCH] powerpc/5200: 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.
