Sorry for that. I lately didn't have time to work on the series.

There are two big open TODOs:

- How should this bridge react if there is no out bridge available, yet? This
  series implements a static approach by returning EPROBE_DEFER from
  bridge_attach if there isn't a next bridge, connector or display. Andrezej
  suggested a dynamic approach which allows to attach this bridge without a
  next bridge and dynamically add further bridges/panels. The latter approach
  didn't work with the mxsfb driver, but I didn't have time to look into this.

- The component framework stuff that allows to use the bridge with the Exynos
  driver should not go into the bridge driver, but stay in the platform part.
