The DT has always supposed to have been the same one as the Linux Kernel, to make things easier for developers as they would only need one DT, not two. For systems that use the EFI loader we pass the same DT to the OS which can simplify life. > Do we need to upstream the kernel DT first? If the DT is not upstream it really should be being submitted upstream and not just never upstreamed. I know this is more challenging in some cases than others. > Do we need to provide a complete "kernel DT" to u-boot as well? That is usually easiest, yes. --=20 Tom --zoAX9RxxNgtVTVsH Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQGzBAABCgAdFiEEGjx/cOCPqxcHgJu/FHw5/5Y0tywFAmWUvbcACgkQFHw5/5Y0 tyxcsAv9HP5DhmUcGUc2aD1v+w4ySnJrca3DhTGsdaLDZXnhYtWrHuAfDFyohgDH VwwBsfxtFiVaWXcAbUue7+1TXwoy5Pny2dBNmo2EcT2joresRtz070obBhMa2U0d YT0WFnvxzjnwASwV3ilknKkjjylIyFFbu7+u/+4E2wDfooUOCkV8tFH02Ouoem7e WraDRrVn2mPaSBGPoe0ZeHuv/tniPB3S6D+Pmk2ZrBW49NeJbCg7+lCfbuaecfaV muiVvu5hteQ1Urax3njCQA161mkc14ZIBPHWvUvxjmy7s7PpOCmTiawV1IaDo2mg 1AHnBf6ulkcYwbxnS9pf1TKviY6dfEMgbzP0MBp3b3TvI6rYGqrsf2RXqUeKcXyf G5rFA0f+/MjonccQA6u3JXiCVwsom6RXBdvUAoVHjCMngkH1jTMLWk7R/jSiIBkJ jL6GSfaq88pkZuXTelwZ84tb6bPdbwU/U3ZU/R/oi7kYNLCmHanV7HUqUg67f28p eLD6Hjjr =LlVx -----END PGP SIGNATURE----- --zoAX9RxxNgtVTVsH--
