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. Signed-off-by:

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. Signed-off-by:

Add V4L2_CID_IMAGE_STABILIZATION control for the camera image stabilization feature. This control can be used to enable/disable image stabilization. It might get converted to a menu control in future if more options are needed. Signed-off-by:

Add V4L2_CID_WIDE_DYNAMIC_RANGE camera class control for the camera wide dynamic range (WDR, HDR) feature. This control can be used to enable/disable wide dynamic range. It might get converted to a menu control in future if more options are needed. Signed-off-by:

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. Signed-off-by:

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.

This patch adds definition of additional color effects: - V4L2_COLORFX_AQUA, - V4L2_COLORFX_ART_FREEZE, - V4L2_COLORFX_SILHOUETTE, - V4L2_COLORFX_SOLARIZATION, - V4L2_COLORFX_ANTIQUE, - V4L2_COLORFX_SET_CBCR. The new V4L2_COLORFX_CBCR control is added to allow setting the fixed Cb, Cr values that replace chroma Cb/Cr coefficients in case of V4L2_COLORFX_SET_CBCR effect. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

af9033: implement read_ber and read_ucblocks functions. Version 2 of patch that reflects my findings on the behaviour of abort_cnt, err_cnt and bit_cnt: - bit_cnt is always 0x2710 (10000) - abort_cnt is between 0 and 0x2710 - err_cnt is between 0 and 640000 (= 0x2710 * 8 * 8) in the current implementation BER is calculated as the number of bit errors per processed bits, ignoring those bits that are already discarded and counted in abort_cnt, i.e. UCBLOCKS.

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 we don't know how to lower the brightness setting when not vflipping, simply always vflip and tell userspace to flip the image back, resulting in a much better (less washed out) image. Since the image is now no longer too bright, also modify the luminance level the auto-gain algorithm aims for. Signed-off-by:

Our init sequence was not setting the register page to point to bank 1 before setting what should be the control reg. This causes the camera to sometimes have its LED on after init. First selecting register bank 1, rather then assuming the current register bank is bank 1, fixes this. Signed-off-by:

The pac207's exposure control is a clock-divider, so it goes with quite big steps. So lets use an autogain algorithm optimised for that. Signed-off-by:
