[PATCH v4 0/6] MT9M114 driver bugfix and improvements

[Mathis Foerst <mathis.foerst@mt.com>]

Hi,

this patch series contains the following bugfix and improvements
for the MT9M114 camera driver:

Changelog:

v3 -> v4:
- Rename DT binding from "onnn,slew-rate" to "slew-rate" in PATCH 1 and 6 as
  requested in the review comment.

v2 -> v3:
- Dropped PATCH 2 ("media: mt9m114: Add get_mbus_config").
  Based on the comments, this issure won't be fixed in the MT9M114
  driver but in "imx-media-csi.c" in a separate patch.
- Renumbered patches accordingly.
- Fix the incomplete renaming of the DT property from 'pad-slew-rate'
  to 'onnn,slew-rate' in PATCH 1 and 6.
- Fix checkpatch formatting suggestions in PATCH 2 and 6.

v1 -> v2:
- Fix the subjects of the patches
- Dropped PATCH 1 ("Add bypass-pll DT-binding") as it can be automatically
  detected if the PLL should be bypassed.
- Renumbered patches accordingly
- Switch to uint32, add default value and clarify documentation in PATCH 1
- Add 'Fixes' and 'Cc' tags as suggested in PATCH 6

Bugfixes:
- Fix a deadlock when using the V4L2 pad-ops get/set_frame_interval

New Features:
- Bypass the internal PLL if EXTCLK matches the configured link_frequency
- Make the slew-rate of the output pads configurable via DT
- Allow to change the cropping configuration and the horizontal/vertical
  flipping while the sensor is in streaming state

Thanks,
Mathis
