This set of changes reorganises imx-drm's DT bindings by re-using the OF
graph parsing code which was located in drivers/media, removing the
temporary bindings.
The result is that more TODO entries are now removed. While we're not
quite done with this yet as there's a few straggling updates to imx-ldb
to come, but leaving these out is not detrimental at this point in time
- they are more an enhancement.
However, this pull has the additional complication that we're sharing
seven commits with Mauro's V4L git tree, which move the OF graph parsing
code out of drivers/media into drivers/of. Philipp's imx-drm changes
depend on these and my previously committed round of imx-drm commits.
Hence, the diffstat below is from a test merge with your tree head
(17b02809cf).
Mauro merged those seven commits earlier today as a git pull, so both
trees will be sharing exactly the same commit IDs.
I've given these changes a spin here on both my Hummingboard and Cubox-i4
(one is iMX6Solo, the other is iMX6Quad based), which includes Xorg using
the DRM device directly, and I find nothing wrong.
The diffstat does look a little scarey - this is because we're having to
update the ARM DT files along with this change, and obviously the
dependency on the OF graph parsing code.
