From e22242141331bc829ecca194f5c06f674da618ef Mon Sep 17 00:00:00 2001 From: =?utf8?q?C=C3=A9dric=20Le=20Goater?= Date: Fri, 8 Jun 2018 13:15:32 +0100 Subject: [PATCH] smbus: add a smbus_eeprom_init_one() routine MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This is an helper routine to add a single EEPROM on an I2C bus. It can be directly used by smbus_eeprom_init() which adds a certain number of EEPROMs on mips and x86 machines.
