i2c: Constify i2c_client where possible

2011-01-10T21:11:23Z

Helper functions for I2C and SMBus transactions don't modify the i2c_client that is passed to them, so it can be marked const. Signed-off-by: Jean Delvare

i2c: Mark i2c_adapter.id as deprecated

2010-11-15T21:40:38Z

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. Signed-off-by: Jean Delvare Acked-by: Jarod Wilson Acked-by: Mauro Carvalho Chehab Acked-by: Hans Verkuil

i2c: Drop unused I2C_CLASS_TV flags

2010-10-31T20:06:59Z

There are no users left for I2C_CLASS_TV_ANALOG and I2C_CLASS_TV_DIGITAL, so we can get rid of them. Signed-off-by: Jean Delvare

i2c: Let i2c_parent_is_i2c_adapter return the parent adapter

2010-10-24T16:16:57Z

This makes the calling site's code clearer IMHO. Signed-off-by: Jean Delvare Acked-by: Michael Lawnick

i2c: Simplify i2c_parent_is_i2c_adapter

2010-10-24T16:16:57Z

Only i2c devices can have their type set to i2c_adapter_type, so testing the bus type is redundant. Signed-off-by: Jean Delvare Cc: Michael Lawnick

i2c: Multiplexed I2C bus core support

2010-08-11T16:21:02Z

Add multiplexed bus core support. I2C multiplexer and switches like pca954x get instantiated as new adapters per port. Signed-off-by: Michael Lawnick Acked-by: Rodolfo Giometti Signed-off-by: Jean Delvare

i2c: Use a separate mutex for userspace client lists

2010-08-11T16:21:01Z

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. Signed-off-by: Jean Delvare Cc: Michael Lawnick

i2c: Move adapter locking helpers to i2c-core

2010-08-11T16:20:58Z

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. Signed-off-by: Jean Delvare Cc: Michael Lawnick

V4L/DVB: Use custom I2C probing function mechanism

2010-08-11T16:20:57Z

Now that i2c-core offers the possibility to provide custom probing function for I2C devices, let's make use of it. Signed-off-by: Jean Delvare Acked-by: Mauro Carvalho Chehab

i2c: Add support for custom probe function

2010-08-11T16:20:56Z

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. Signed-off-by: Jean Delvare Acked-by: Mauro Carvalho Chehab
