[PATCH] 1/5 powerpc: Rework PowerMac i2c part 1
This is the first part of a rework of the PowerMac i2c code. It completely reworks the "low_i2c" layer. It is now more flexible, supports KeyWest, SMU and PMU i2c busses, and provides functions to match device nodes to i2c busses and adapters. This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
