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. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
