[src/trunk]: src/sys/arch/macppc overhaul SMU i2c handling:
details: https://anonhg.NetBSD.org/src/rev/d4bb68850de1
branches: trunk
changeset: 318397:d4bb68850de1

description:
overhaul SMU i2c handling:
- get rid of the special smuiicbus, use generic i2cbus
- use shifted i2c addresses like everyone else
- use direct config
with this generic i2c drivers should work on the smu's i2c bus.
