Ionut Gabriel Popescu 23f0cb62ba V4L/DVB: mt9v022.c: Fixed compilation warning
The drivers/media/video/mt9v022.c file, on line 405, tries a "case 0" o a
v4l2_mbus_pixelcode enum which don't have an 0 value element, so I got a compile
warning. That "case" is useless so it can be removed.

Wolfram Sang fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

enum_mbus_fmt received an index argument that was defined as an int instead
of an unsigned int. This is now fixed. This had the knock-on effect that the
index argument in the callback get_formats in soc_camera.h also had to be
changed to unsigned int.

Guennadi Liakhovetski 594bb46dbc V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_link
Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.

Since the i2c driver ID will be removed in the near future we have to

Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.

Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

with this config:

   http://redhat.com/~mingo/misc/config-Sat_May__3_16_08_39_CEST_2008.bad

the bug was that the driver uses GPIO functionality but only includes
the GPIO interface definitions for the CONFIG_MT9M001_PCA9536_SWITCH
case, which was not set in this config.

The quick fix seems to be to include linux/gpio.h unconditionally. (this
seems like a small cleanup as well as it removes and #ifdef is more
robust than an inclusion of asm/gpio.h) Not tested too much yet, so
please have another look in any case.

Jean Delvare 3760f73671 i2c: Convert most new-style drivers to use module aliasing
Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

Jean Delvare d2653e9273 i2c: Add support for device alias names
Based on earlier work by Jon Smirl and Jochen Friedrich.

This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.

pixel clock polarity shall be set depending on capabilities of the

Guennadi Liakhovetski ef6ad5c35e V4L/DVB (7218): Fix breakage in mt9m001 and mt9v022 driver if "CONFIG_GENERIC_GPIO is not set"
Both camera drivers can function without GPIO support, in which case they
will only support the 10 bit data width mode. But the two respective switch
have to depend on CONFIG_GENERIC_GPIO. Additionally remove redundant
gpio_is_valid tests - they are repeated in bus_switch_request() functions.
