 Do you mind dual licence those header under GPL/MIT like the others ?
 We currently dont use those directly in FreeBSD but we should (and
will soon) and we can't if they are only GPL.

 Thanks.

 We use HDMI (not HDMI1) on FreeBSD (see
https://svnweb.freebsd.org/base/head/sys/boot/fdt/dts/arm/sun7i-a20-hdmi.dtsi?revision=308672&view=markup#l71)

 If you could define it in your patch this will be great.
