i2c: remove FSF address

2014-11-07T17:35:33Z

We have a central copy of the GPL for that. Some addresses were already outdated. Signed-off-by: Wolfram Sang

i2c: i2c-dev: Create 'name' attribute automatically

2013-09-30T04:02:31Z

The 'name' attribute is needed for all i2c-dev class devices, meaning it can be created automatically by pointing to it in the class data structure. This simplifies the code and reduces the probability for race conditions (the name attribute should exist by the time the device is announced to user space).

i2c-dev: Add support for I2C_M_RECV_LEN

2012-05-30T08:55:34Z

As the bus driver side implementation of I2C_M_RECV_LEN is heavily tied to SMBus, we can't support received length over 32 bytes, but let's at least support that. In practice, the caller will have to setup a buffer large enough to cover the case where received length byte has value 32, so minimum 32 + 1 = 33 bytes, possibly more if there is a fixed number of bytes added for the specific slave (for example a checksum.)

i2c-dev: Use memdup_user

2012-01-12T19:32:04Z

Use memdup_user rather than duplicating its implementation. This is a little bit restricted to reduce false positives. The semantic patch that makes this output is available in scripts/coccinelle/api/memdup_user.cocci.

i2c: Make i2cdev_notifier_call static

2011-11-23T10:33:07Z

The function i2cdev_notifier_call is used only in i2c-dev file making it static. Also removes the following sparse warning drivers/i2c/i2c-dev.c:582:5: warning: symbol 'i2cdev_notifier_call' was not declared. Should it be static? Signed-off-by: Shubhrajyoti D Signed-off-by: Jean Delvare

i2c-dev: Use standard bus notification mechanism

2011-03-20T13:50:52Z

Use the standard driver core mechanism to keep track of i2c adapters present on the system: i2c_for_each_dev and a notifier. This will let us deprecate and ultimately remove the legacy attach_adapter and detach_adapter callbacks in i2c_driver. 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: 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
