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.

  • As I understand, DT-overlays should be used to add are change properties in the device tree. So, if I understand this correctly, it shiould activate properties from add-on boards, for example a DAC or Wifi board as available for pine64. So in this case, it should be good to add support for the wifi board and also the audio pot board on the pine64 boards .

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


    Thanks for suggestions!

  • H2+ ethernet - most important

    H2+ i2c0, i2c1

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

    Thanks!

  • 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.
