Hi Andrei,
I don't quite get your query. I am answering in a presumption that you
are enquiring about the sam9x7.dtsi file presence.
This file arch/arm/boot/dts/microchip/sam9x7.dtsi is being added in this
very series by patch 25/27. It is not yet applied, hence will not be
available in any of the upstream repos.
(P.S.: Sorry for the noise and the wide audience)
