[PATCH v7 0/3] drm/atmel-hlcdc: bus-width override support

[Peter Rosin]

Hi!

The background for these patches is that our PCB interface between
the SAMA5D3 and the ds90c185 lvds encoder is only using 16 bits, and
this has to be described somewhere, or the atmel-hlcdc driver have no
chance of selecting the correct output mode. Since we have similar
problems with a tda19988 HDMI encoder I added patches to override
the atmel-hlcdc output format via DT properties compatible with the
media video-interface binding and things start to play together.

Cheers,
Peter

Changes since v6  https://lkml.org/lkml/2018/8/3/333
- zap bus-type from the binding in patch 2/3

Changes since (the shortened) v5  https://lkml.org/lkml/2018/8/3/182
- add reg properties (and #*-cells) to the example in patch 2/3
- prohibit bus-width 0 in the device-tree in patch 3/3
- added reviewed-by from Jacopo to patch 2/3 and 3/3
