* [media] V4L: Add camera scene mode controlSylwester Nawrocki2012-05-143-0/+156
| | | | | | | | | | | | | Add control for the scene mode feature available in image sensor with more advanced ISP firmware. The V4L2_CID_SCENE_MODE menu control allows to select a set of parameters or a specific image processing and capture control algorithm optimized for common image capture conditions.

* [media] V4L: Add camera ISO sensitivity controlsSylwester Nawrocki2012-05-144-0/+67
| | | | | | | | | | | Add ISO sensitivity and ISO auto/manual controls. The sensitivity values are related to level of amplification of the analog signal between image sensor and ADC. These controls allow to support sensors exposing an interface to accept the ISO values directly.

* [media] V4L: Add an extended camera white balance controlSylwester Nawrocki2012-05-143-0/+101
| | | | | | | | | | | | | | | | | | | | | This patch adds V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE control which is an extended version of the V4L2_CID_AUTO_WHITE_BALANCE control, including white balance presets. The following presets are defined: - V4L2_WHITE_BALANCE_INCANDESCENT, - V4L2_WHITE_BALANCE_FLUORESCENT, - V4L2_WHITE_BALANCE_FLUORESCENT_H, - V4L2_WHITE_BALANCE_HORIZON, - V4L2_WHITE_BALANCE_DAYLIGHT, - V4L2_WHITE_BALANCE_FLASH, - V4L2_WHITE_BALANCE_CLOUDY, - V4L2_WHITE_BALANCE_SHADE.

* [media] V4L: Add camera exposure bias controlSylwester Nawrocki2012-05-143-0/+22
| | | | | | | | | | | | The camera may in some conditions incorrectly determine the exposure, and a manual automatic exposure correction may be needed. This patch adds V4L2_CID_AUTO_EXPOSURE_BIAS control which allows to add some offset in the automatic exposure control loop, to compensate for frame under- or over-exposure.

* [media] V4L: Add helper function for standard integer menu controlsSylwester Nawrocki2012-05-143-0/+59
| | | | | | | | | | | | | | This patch adds v4l2_ctrl_new_int_menu() helper function which can be used in drivers for creating standard integer menu control with driver-specific menu item list. It is similar to v4l2_ctrl_new_std_menu(), except it doesn't have a mask parameter and an additional qmenu parameter allows passing an array of signed 64-bit integers as the menu item list.

* [media] radio-si470x-usb: remove autosuspend, implement suspend/resumeHans Verkuil2012-05-142-80/+70
| | | | | | | | | | | | | | | | | | | | | | The radio-si470x-usb driver supported both autosuspend and it stopped the radio the moment the last user of the radio device closed it. However, that was very confusing since if you play the audio from the device (e.g. through arecord -D ... | aplay) then no sound would play unless you had the radio device open at the same time, even though there is no need to do anything with that node. On the other hand, the actual suspend/resume functions didn't do anything, which would fail if you *did* have the radio node open at that time. So: - remove autosuspend (bad idea in general for USB radio devices) - move the start/stop out of the open/release functions into the resume/suspend functions.

* [media] mt9v032: Correct the logic for the auto-exposure settingKartik Mohta2012-05-141-1/+1
| | | | | | | | | | | | The driver uses the ctrl value passed in as a bool to determine whether to enable auto-exposure, but the auto-exposure setting is defined as an enum where AUTO has a value of 0 and MANUAL has a value of 1. This leads to a reversed logic where if you send in AUTO, it actually sets manual exposure and vice-versa.

| | | | | | | | | | | | | | | Enabling vflip leads to a much better image, with vflip disabled the image looks washed out as if there is a too high brightness setting.

Since the image is now no longer too bright, also modify the luminance level the auto-gain algorithm aims for.

* [media] gspca_zc3xx: Fix JPEG quality setting codeHans de Goede2012-05-141-42/+22
| | | | | | | | | | | | | | | | | | | The current code is using bits 0-1 of register 8 of the zc3xx controller to set the JPEG quality, but the correct bits are bits 1-2. Bit 0 selects between truncation or rounding in the quantization phase of the compression, since rounding generally gives better results it should thus always be 1. This patch also corrects the quality percentages which belong to the 4 different settings. Last this patch removes the different reg 8 defaults depending on the sensor type. Some of them where going for a default quality setting of 50%, which generally is not necessary in any way and results in poor image quality. 75% is a good default to use for all scenarios.
