Hi All,

Here is v2 of my series to make the "mainline" mt9m114 driver work
on devices with an atomisp CSI2 receiver / ISP. This has been tested on
an Asus T100TA.

Changes in v2:
- Rebase on top of sailus/media_tree.git/fixes which now has 4 of
  the patches from Mathis': "MT9M114 driver bugfix and improvements"
  series, this avoids most of the conlicts between the 2 series
- Add Laurent's Reviewed-by to some of the patches
- Add select VIDEO_APTINA_PLL to Kconfig
- Use correct aptina_pll_limits
- After setting reset high wait 20 clk cycles before disabling
  the clk and regulators
- When bypassing the scalar make ifp_get_selection() / ifp_set_selection()
  fill sel->r with a rectangle of (0,0)/wxh and return 0 instead of
  returning -EINVAL

Regards,

Hans
