Subject: [PATCH v2 0/7] MT9M114 driver bugfix and improvements

Hi,

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

Changelog:
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

Link to v1 discussion:
https://lore.kernel.org/linux-media/20250226153929.274562-1-mathis.foerst@mt.com/


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

Compatibility:
- Implement the missing get_mbus_config() function to be compatible
  with the i.MX6 camera framework

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
