[media] cec: select CEC_CORE instead of depend on it

2017-06-04T18:23:33Z

The CEC framework is used by both drm and media. That makes it tricky to get the dependencies right. This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options out of the media menu and instead drivers that want to use CEC should select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

[media] ov2640: fix vflip control

2017-04-19T12:01:09Z

Enabling vflip currently causes wrong colors. It seems that (at least with the current sensor setup) REG04_VFLIP_IMG only changes the vertical readout direction. Because pixels are arranged RGRG... in odd lines and GBGB... in even lines, either a one line shift or even/odd line swap is required, too, but apparently this doesn't happen. I finally figured out that this can be done manually by setting REG04_VREF_EN. Looking at hflip, it turns out that bit REG04_HREF_EN is set there permanetly, but according to my tests has no effect on the pixel readout order. So my conclusion is that the current documentation of sensor register 0x04 is wrong (has changed after preliminary datasheet version 2.2). I'm pretty sure that automatic vertical line shift/switch can be enabled, too, but until anyone finds ot how this works, we have to stick with manual switching.

[media] ov2640: fix duplicate width+height returning from ov2640_select_win()

2017-04-19T11:58:41Z

ov2640_select_win() returns height and width values as part of struct ov2640_win_size, so there is no point in modifying the passed height and width parameters, too. Signed-off-by: Frank Schäfer Signed-off-by: Mauro Carvalho Chehab

[media] ov2640: add information about DSP register 0xc7

2017-04-19T11:55:07Z

According to ov2640 software application notes, there are two Automatic White Balance (AWB) modes, which are selected by DSP register 0xc7: 1) Simple AWB: assumes the average color is gray + independent from lens - doesn't work well if captured area contains unbalanced colors (e.g. large blue background) 2) Advanced AWB: uses color temperature information + more accurate, works with all image contents - lens specific, requires calibration Signed-off-by: Frank Schäfer Signed-off-by: Mauro Carvalho Chehab

[media] ov2640: improve banding filter register definitions/documentation

2017-04-19T11:54:35Z

- add missing initialisation of sensor register COM25 (2 MSBs of banding filter AEC values) - add macros for setting the banding filter AEC values - add definitions for sensor register 0x5a, which is documented in Omnivisions software application notes Signed-off-by: Frank Schäfer Signed-off-by: Mauro Carvalho Chehab
