Benjamin Herrenschmidt 9f2545c118 [POWERPC] Fix i2c-powermac platform device usage
i2c-powermac was written & merged right after Russell King's changes
adding platform_driver... which I missed. Thus it still used struct
device, causing crashes when hitting sleep/wakeup callbacks (it happened
to work by luck so far, until early/late callbacks got added). This
causes crashes on sleep/wakeup on PowerBooks with 2.6.19. The patch
fixes it by using a proper platform_driver.

i2c: Constify i2c_algorithm declarations, part 2

Make struct i2c_algorithm declarations const in all i2c bus drivers
where it is possible.

Jeremy Kerr 018a3d1db7 [POWERPC] powermac: Constify & voidify get_property()
Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

powermac platform & macintosh driver changes.

Built for pmac32_defconfig, g5_defconfig

Jean Delvare 8ced8eee85 [PATCH] i2c-powermac: Fix master_xfer return value
Fix the value returned by the i2c-powermac's master_xfer method.
It should return the number of messages processed successfully, but
instead returns the number of data bytes in the first (and only)
processed message.

Also explicitly mention the master_xfer convention so that future
implementations get it right directly.

Benjamin Herrenschmidt a28d3af2a2 [PATCH] 2/5 powerpc: Rework PowerMac i2c part 2
This is the continuation of the previous patch. This one removes the old
PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them
both with a single stub driver that uses the new PowerMac low i2c layer.

Now that i2c-keywest is gone, the low-i2c code is extended to support
interrupt driver transfers. All i2c busses now appear as platform
devices. Compatibility with existing drivers should be maintained as the
i2c bus names have been kept identical, except for the SMU bus but in
that later case, all users has been fixed.

With that patch added, matching a device node to an i2c_adapter becomes
trivial.
