From f5b728a164b22ec38a5657ebe038def36ffae98b Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 14 Jul 2008 22:38:23 +0200 Subject: i2c: Group bus drivers by type The list of I2C/SMBus bus drivers is growing and it is sometimes difficult for the users to figure out what drivers they should enable. By grouping the drivers by type, I hope to make the selection easier.
