i2c: Improve deprecation warnings

2011-04-17T08:20:19+00:00

When warning on the use of deprecated i2c_driver methods
attach_adapter and detach_adapter, mention the name of the driver
which needs to be updated.

i2c: Deprecate i2c_driver.attach_adapter and .detach_adapter

2011-03-20T13:50:53+00:00

The last legitimate user of i2c_driver.attach_adapter and
.detach_adapter is gone, so we can finally deprecate these callbacks.
The last few drivers which still use these will have to be updated to
make use of standard I2C device instantiation ways instead.

i2c: Export i2c_for_each_dev

2011-03-20T13:50:52+00:00

Introduce i2c_for_each_dev(), an i2c device iterator with proper
locking for use by i2c-dev. This is needed so that we can get rid of
the attach_adapter and detach_adapter legacy callback functions.

i2c: make i2c_get_adapter prototype clearer

2011-03-20T13:50:52+00:00

Rename the parameter of i2c_get_adapter() to "nr", to make it clear we
are passing an adapter number and not an adapter ID (which have gone
away by now.)

driver-core: remove conditionals around devicetree pointers

2011-01-21T16:24:48+00:00

Having conditional around the of_match_table and the of_node pointers
turns out to make driver code use ugly #ifdef blocks.  Drop the
conditionals and remove the #ifdef blocks from the affected drivers.

Also tidy up minor whitespace issues within the same hunks.

i2c: Encourage move to dev_pm_ops by warning on use of legacy methods

2011-01-14T21:03:50+00:00

Since the PM core wishes to transition away from the legacy suspend
and resume methods and since removing them makes using PM core features
like runtime PM much easier start warning when a driver is registered
using the legacy methods.

i2c: Factor out runtime suspend checks from PM operations

2011-01-14T21:03:49+00:00

When devices use dev_pm_ops the I2C API is implementing standard functionality
for integration with runtime PM and for checking for the presence of a per
device op. The PM core provides pm_generic_ functions implementing this
behaviour - use them to reduce coupling with future PM updates.

i2c: Unregister dummy devices last on adapter removal

2011-01-14T21:03:49+00:00

Remove real devices first and dummy devices last. This gives device
driver which instantiated dummy devices themselves a chance to clean
them up before we do.

i2c: Constify i2c_client where possible

2011-01-10T21:11:23+00:00

Helper functions for I2C and SMBus transactions don't modify the
i2c_client that is passed to them, so it can be marked const.
