Subject: [PATCH v3 0/5] General RK3368 HDMI support and 2 outputs for RK3368-Lion

This series adds the necessary bits for HDMI output on RK3368 and enables
this on RK3368-Lion. At the same time, use the recently added DSI support
to enable the generic Video-Demo-adapter as an overlay on Lion as well.


The reason I'm shaving this Yak is that the recently added DSI support
created DTC warnings about a single endpoint with an address.

So it was either removing the @0 from the endpoint, or adding a second
output option :-) .


changes in v3:
- drop patches that already are applied
- added Quentin's Rb tags (except the one on hdmi enablement)
- moved hdmi supplies to lion.dtsi
- move bl-pwm enablement into a separate patch (and to haikou)

changes in v2:
- pick up Conor's Ack for the compatible
- fix the spelling errors reported by Diederik
