DT overlay support

Hi all,

I'm working on DT overlay support (initial PR here: Allwinner: Support for DT overlays by jernejsk · Pull Request #4788 · LibreELEC/LibreELEC.tv · GitHub). Most infrastructure is in place but there is only one overlay included - H6 IR. What I need is some ideas which overlays would be popular so they should be included in image by default. Note I don't intend to include overlays which would be useful for only one or two users. Such overlays can be manually added - they won't be touched with updates (unless they become part of default overlay collection).

My next overlay idea:

H2+ ethernet

Please comment with DT overlay ideas.

Ah yes, pine64 wifi - I forgot about it. I'll check audio board - I don't have it...

Thanks for suggestions!

H2+ IR (banana pi m2 zero don't have ir pin, is it possible use other pin with DT support?)

No, chip supports HW IR only on one pin. However, GPIO variant is possible but for that I won't include overlay, too much options.

PR is now ready: Allwinner: Support for DT overlays by jernejsk · Pull Request #4788 · LibreELEC/LibreELEC.tv · GitHub

Only few overlays are present for now, but most importantly, users can add their own overlays without fear that they will be overwritten with next update.
