From 0365ba7fb1fa94a41289d6a3d36b4d95960e56cc Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 22 Sep 2005 21:44:06 -0700 Subject: [PATCH] ppc64: SMU driver update & i2c support The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.
