Hi Grant,
The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated. This patches
makes all readers of the following elements use device.of_node instead.
struct dev_archdata.prom_node (sparc)
struct dev_archdata.of_node (powerpc)
struct o

Makes sense. I2C transactions better shouldn't be interrupted or
data loss might happen.

Fix build breakage introduced in commit
"[POWERPC] i2c: OF helpers for the i2c API".
If i2c-core is compiled as module, the helper needs to be
compiled as module, as well. Rename i2c.c to of_i2c.c to
avoid name space conflict.

The OF helpers patch depends on the patches below to support autoloading
i2c modules using the a

unfortunately, i2c_new_device() tries to attach the module, so this function
really needs full i2c

I would keep the cpm2 name. I'll just add a comment to cpm1.c that

I guess most of this should go to cpm_common.c and should be used for
Port E on CPM1, as well. This port uses the same layout as CPM2 while

Based on earlier work by Jon Smirl and Jean Delvare.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.
