      media: ak7375: Add ak7375 lens voice coil driver · 90ee26fb
      由 Bingbu Cao 提交于 
      Add a v4l2 sub-device driver for the ak7375 lens voice coil.
This is a voice coil module using the i2c bus to control the
focus position.

ak7375 can write multiple bytes of data at a time. If more
data is received instead of the stop condition after receiving
one byte of data, the address inside the chip is automatically
incremented and the data is written into the next address.

The ak7375 can control the position with 12 bits value and
consists of two 8 bit registers show as below:
register 0x00(AK7375_REG_POSITION):
    +---+---+---+---+---+---+---+---+
    |D11|D10|D09|D08|D07|D06|D05|D04|
    +---+---+---+---+---+---+---+---+
register 0x01:
    +---+---+---+---+---+---+---+---+
    |D03|D02|D01|D00|---|---|---|---|
    +---+---+---+---+---+---+---+---+

This driver support :
    - set ak7375 to standby mode once suspend and
      turn it back to active if resume
    - set the position via V4L2_CID_FOCUS_ABSOLUTE ctrl

      media: ov6650: convert to standalone v4l2 subdevice · 23a52386
      由 Janusz Krzysztofik 提交于 
      Remove the soc_camera dependencies and move the diver to i2c

Lost features, fortunately not used or not critical on test platform:
- soc_camera power on/off callback - replaced with clock enable/disable
  only, no support for platform provided regulators nor power callback,
- soc_camera sense request - replaced with arbitrarily selected default
  master clock rate and pixel clock limit, no support for platform
  requested values,
- soc_camera board flags - no support for platform requested mbus config
  tweaks.

Tested on Amstrad Delta with now out of tree but still locally
maintained omap1_camera host driver.

      [media] ov2640: make GPIOLIB an optional dependency · a463ea99
      由 Mauro Carvalho Chehab 提交于 
      As warned by kbuild test robot:
	warning: (VIDEO_EM28XX_V4L2) selects VIDEO_OV2640 which has unmet direct dependencies (MEDIA_SUPPORT && VIDEO_V4L2 && I2C && GPIOLIB && MEDIA_CAMERA_SUPPORT)

The em28xx driver can use ov2640, but it doesn't depend
(or use) the GPIOLIB in order to power off/on the sensor.

So, as we want to allow both usages with and without
GPIOLIB, make its dependency optional.

      [media] cec: Kconfig cleanup · 56a263aa
      由 Hans Verkuil 提交于 
      The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.
