Hi Nuttx Dev,
We are negotiating with the authors of the linux device driver for the CTU
CAN FD IP core to it re-licenced from GPL to so the driver can then be
ported to Nuttx.
Just a reminder: Apache policy prohibits GPL code, or GPL-derived code,
from being included in any ASF project:
https://apache.org/legal/resolved#category-x
If there is *any* question about the license of incoming code, then you
should ask the Legal Affairs Committee for advice, after reviewing the
ASF policy on source headers:
https://apache.org/legal/src-headers.html
Specific questions (i.e. about a specific body of code under license X
that the project wants to incorporate) should be asked on Jira:
https://issues.apache.org/jira/projects/LEGAL/issues

I've seen various licencing examples in the nuttx code base: but no high
level description that gives a definitive answer. For example there are
some cases where Authors are preserved and the code is BSD-2-Clause or
BSD-3-Clause (not Apache-2.0).
We would appreciate some feedback on whether the proposal from Pavel below
is acceptable or if any minor adjustments would help.
Kind regards,
