Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

2013-11-18T23:50:07+00:00

Pull i2c changes from Wolfram Sang:
 - new drivers for exynos5, bcm kona, and st micro
 - bigger overhauls for drivers mxs and rcar
 - typical driver bugfixes, cleanups, improvements
 - got rid of the superfluous 'driver' member in i2c_client struct This
   touches a few drivers in other subsystems.  All acked.

[media] v4l2-ctrls: Correct v4l2_ctrl_get_int_menu() function's return type

2013-10-17T09:09:55+00:00

Remove the redundant 'const' qualifiers from the function
signature and from the qmenu_int arrays' declarations.

media: core: Don't use i2c_client->driver

2013-10-03T20:28:23+00:00

The 'driver' field of the i2c_client struct is redundant and is going to be
removed. The results of the expressions 'client->driver.driver->field' and
'client->dev.driver->field' are identical, so replace all occurrences of the
former with the later.

v4l2-common: warning fix (W=1): add a missed function prototype

2013-08-18T13:18:30+00:00

changeset d1e9b7c12 added a new ancilliary function to API, but forgot
to add it to the corresponding header file.

[media] v4l2: move dv-timings related code to v4l2-dv-timings.c

2013-08-18T11:16:54+00:00

v4l2-common.c contained a bunch of dv-timings related functions.
Move that to the new v4l2-dv-timings.c which is a more appropriate
place for them.
There aren't many drivers that do HDTV, so it is a good idea to separate
common code related to that into a module of its own.

[media] v4l2: remove obsolete v4l2_chip_match_host()

2013-06-21T13:30:54+00:00

This function is no longer needed since it is now the responsibility of the
v4l2 core to check if the DBG_G/S_REGISTER and DBG_G_CHIP_INFO ioctls are
called for the bridge driver or not.

[media] v4l: Helper function for obtaining timestamps

2012-12-21T12:53:43+00:00

v4l2_get_timestamp() produces a monotonic timestamp but unlike
ktime_get_ts(), it uses struct timeval instead of struct timespec, saving
the drivers the conversion job when getting timestamps for v4l2_buffer's
timestamp field.

[media] v4l2-common: add CVT and GTF detection functions

2012-09-13T19:09:59+00:00

These two helper functions detect whether the analog video timings detected
by the video receiver match the VESA CVT or GTF standards.

They basically do the inverse of the CVT and GTF modeline calculations.

This patch also adds a helper function that will determine the aspect ratio
based on the provided EDID values. This aspect ratio can be given to the GTF
helper function.
