[PATCH v2 2/2] ARM: dts: at91: sama5d2: add ETM and ETB nodes

[Olivier Schonken]

Hi All

Just wondering if there are still some issues regarding the sama5d2
ETM and ETB nodes patch that I have to change/update.
If I should resend at a better time for it to not get lost in the
noise just let me know.

I see that I accidentily left Boris out in the initial resend of the
patch.  My apologies.  Will forward the initial send to him as well.

Regards

Olivier Schonken
