2012-03-08[media] convert drivers/media/* to use module_i2c_driver()Axel Lin
This patch converts the drivers in drivers/media/* to use the module_i2_driver() macro which makes the code smaller and a bit simpler.

2011-11-03[media] V4L: soc-camera: make (almost) all client drivers re-usable outside ↵Guennadi Liakhovetski
of the framework The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
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 e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 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.

2010-05-18V4L/DVB: mt9t031: use runtime pm support to restore ADDRESS_MODE registersValentin Longchamp
If the platform hooks are provided, soc_camera powers off the device on close and powers it on on open. This resets the ADDRESS_MODE registers which then can be different to the value the driver has computed for them. This patch setups runtime pm usage for mt9t031 and uses the resume function to write the ADDRESS_MODE registers in order to fix the above described problem.
