* [media] Add GS1662 driver, a video serializerCharles-Antoine Couret2016-09-195-1/+484
| | | | | | | | | | | | | | You can read datasheet here: http://www.c-dis.net/media/871/GS1662_Datasheet.pdf It's a component which supports HD and SD CEA or SDI formats to SDI output. It's configured through SPI bus. GS1662 driver is implemented as v4l2 subdev.

| | | | | | | | | | | | | | | | | | | | | | This patch removes the soc_camera API dependency from pxa_camera. In the current status : - all previously captures are working the same on pxa270 - the s_crop() call was removed, judged not working (see what happens soc_camera_s_crop() when get_crop() == NULL) - if the pixel clock is provided by then sensor, ie. not MCLK, the dual stage change is not handled yet. => there is no in-tree user of this, so I'll let it that way - the MCLK is not yet finished, it's as in the legacy way, ie. activated at video device opening and closed at video device closing. In a subsequence patch pxa_camera_mclk_ops should be used, and platform data MCLK ignored. It will be the sensor's duty to request the clock and enable it, which will end in pxa_camera_mclk_ops.
