[PATCH v3 0/8] media: rcar-vin: Brush endpoint properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
   3rd version of VIN endpoint brushing series.

Slightly enlarged the linux-media receiver list, as this new version
introduces a common property in 'video-interfaces.txt'.

Quite some changes compared to v1/v2:
- First patch in the series changed to include Niklas' comments on using
  spaces for indent over tabs in documentation and as suggested by Rob and
  Laurent to refer to 'video-interfaces.txt' in property description.
- As suggested by Rob this series introduces a new property 'data-enable-active'
  to describe data enable signal polarity instead of using 'data-active' which
  refers to the data lanes polarity.
- Use this new property to control CLKENB pin polarity in VIN driver
- Introduce a new custom property to describe the 'use HSYNC as data-enable'
  function provided by VIN. In previous iterations I used the presence of
  'data-active' to enable/disable this functionality. That was confusing and
  not correct as it used the wrong property. As this is a VIN specificity, I
  thought a custom property is more suited.
- Last patch is still there and I know it is debated. My opinion is that it is
  still needed, as the presence of those un-documented and un-parsed properties
  confuses users which may expect changing those properties value to reflect on
  the video interface configuration, which does not happens instead.

Individual changelog per patch when relevant.

Thanks
