I2C: Add helper macro for i2c_driver boilerplate

2012-04-16T10:49:23+00:00

This patch introduces the module_i2c_driver macro which is a convenience macro
for I2C driver modules similar to module_platform_driver. It is intended to be
used by drivers which init/exit section does nothing but register/unregister
the I2C driver. By using this macro it is possible to eliminate a few lines of
boilerplate code per I2C driver.

[ARM]tegra:i2c: Adding i2c slave support apis.

2011-12-01T05:41:51+00:00

To support the i2c slave functionality in the kernel, adding the
framework so that chip specific slave driver can be plugged in.

Adding slave adapter and alogithms in framework so that slave bus driver
can register chip specific driver.

hwmon: (jc42) Change detection class

2011-05-25T18:43:32+00:00

While the JC42-compatible chips are temperature sensors, I2C_CLASS_SPD
makes more sense because these chips always live on memory modules.

i2c: Drop i2c_adapter.id

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

There is no user left of i2c_adapter.id, so we can get rid of it.
Finally! :)

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.

The last remaining ID in  is no longer used anywhere,

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: 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.
