From 6e99806ebb33c1b4906ce4f99eec65d4962f12b9 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 10 May 2007 03:15:52 -0700 Subject: [PATCH] i2c-at91 supports new-style i2c drivers Make i2c-at91 register as i2c adapter zero (none of these chips seem to have more than one TWI controllers) to let it kick in any board-specific device declarations; also make it hotplug/coldplug.
