i2c: Fix sparse warnings for I2C_BOARD_INFO()

2009-04-13T15:02:14+00:00

Since the first argument to I2C_BOARD_INFO() must be a string constant,
there is no need to parenthesise it, and adding parentheses results in
an invalid initialiser for char[].  gcc obviously accepts this syntax as
an extension, but sparse complains, e.g.:

drivers/net/sfc/boards.c:173:2: warning: array initialized from parenthesized string constant

Therefore, remove the parentheses.

i2c: Deprecate client_register and client_unregister methods

2009-04-06T16:12:24+00:00

The new i2c binding model makes the client_register and
client_unregister methods of struct i2c_adapter useless, so we can
remove them with the rest of the legacy model.

i2c-dev: Clarify the unit of ioctl I2C_TIMEOUT

2009-02-24T18:19:49+00:00

The unit in which user-space can set the bus timeout value is jiffies
for historical reasons (back when HZ was always 100.) This is however
not good because user-space doesn't know how long a jiffy lasts. The
timeout value should instead be set in a fixed time unit. Given the
original value of HZ, this unit should be 10 ms, for compatibility.

i2c: Warn on deprecated binding model use

2009-01-26T20:19:57+00:00

Let the kernel developers know that i2c_attach_client() and
i2c_detach_client() are deprecated and should no longer be used.
Drivers using these should be converted to the standard device
driver binding model (probe and remove methods.)

i2c: Drop I2C_CLASS_CAM_DIGITAL

2009-01-07T13:29:17+00:00

There are a number of drivers which set their i2c bus class to
I2C_CLASS_CAM_DIGITAL, however no chip driver actually checks for this
flag, so we might as well drop it now.

i2c: Drop I2C_CLASS_CAM_ANALOG and I2C_CLASS_SOUND

2009-01-07T13:29:17+00:00

There are no users left of these two i2c probe class flags so we can
drop the now.

i2c: Drop I2C_CLASS_ALL

2009-01-07T13:29:16+00:00

I2C_CLASS_ALL is almost never what bus driver authors really want.
These i2c classes are really only about which devices must be probed,
not what devices can be present. As device drivers get converted to the
new i2c device driver model, only a few device types will keep relying
on probing.

i2c: Add info->archdata field

2008-10-22T18:21:33+00:00

If present the info->archdata is copied into the dev->archdata.
Some (OpenFirmware) platforms need it.

i2c: Clean up

2008-10-22T18:21:32+00:00

Fix most checkpatch.pl errors and warnings. This includes replacing
spaces with tabs in many places, adding and removing spaces, and
folding long lines.

Also complete a couple prototypes to make it clearer what the
parameters represent.

i2c: Drop 2-byte address block transfer defines

2008-10-22T18:21:31+00:00

We have no users and no implementers for these transfer types so it
makes little sense to define functionality bits for them.
