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.

i2c: Mark i2c_adapter.id as deprecated

2010-11-15T21:40:38+00:00

It's about time to make it clear that i2c_adapter.id is deprecated.
Hopefully this will remind the last user to move over to a different
strategy.

i2c: Drop unused I2C_CLASS_TV flags

2010-10-31T20:06:59+00:00

There are no users left for I2C_CLASS_TV_ANALOG and
I2C_CLASS_TV_DIGITAL, so we can get rid of them.

i2c: Let i2c_parent_is_i2c_adapter return the parent adapter

2010-10-24T16:16:57+00:00

This makes the calling site's code clearer IMHO.

i2c: Simplify i2c_parent_is_i2c_adapter

2010-10-24T16:16:57+00:00

Only i2c devices can have their type set to i2c_adapter_type, so
testing the bus type is redundant.

i2c: Multiplexed I2C bus core support

2010-08-11T16:21:02+00:00

Add multiplexed bus core support. I2C multiplexer and switches
like pca954x get instantiated as new adapters per port.

i2c: Use a separate mutex for userspace client lists

2010-08-11T16:21:01+00:00

Moving userspace-instantiated clients to separate lists wasn't nearly
enough to avoid deadlocks in multiplexed bus cases. We also want to
have a dedicated mutex to protect each list.

i2c: Move adapter locking helpers to i2c-core

2010-08-11T16:20:58+00:00

Uninline i2c adapter locking helper functions, move them to i2c-core,
and use them in i2c-core itself. The functions are still exported for
external users. This makes future updates to the locking model (which
will be needed for multiplexing support) possible and transparent.

V4L/DVB: Use custom I2C probing function mechanism

2010-08-11T16:20:57+00:00

Now that i2c-core offers the possibility to provide custom probing
function for I2C devices, let's make use of it.

i2c: Add support for custom probe function

2010-08-11T16:20:56+00:00

The probe method used by i2c_new_probed_device() may not be suitable
for all cases. Let the caller provide its own, optional probe
function.
