Add the missing CAN devices node including their pin muxing to the shared
.dtsi for at91sam9x5. Actually include this file.
While at it, fix white spaces of can1_clk.

Well, no: I split the patch in two to separate these whitespace
modifications and the addition of nodes. But now worries, I did it and
stacked the 2 patches on top of my WIP at91-3.19-dt branch.

(FYI, the additional patch is named (ARM: at91/dt/trivial:
at91sam9x5_can.dtsi: comment and whitespace fixes))

I also added the Acked-by from Alexandre Belloni as he added it in a
previous version and confirmed it on IRC for this v4.

Thanks for your help Alexander. Bye,

It seems this branch is not public, yet. At least I could not find it on git.kernel.org.
Did you also pick "ARM: at91/dt: sam9263: Add CAN device nodes"? (https://www.mail-archive.com/devicetree@vger.kernel.org/msg44970.html)

Best regards,
Alexander

I've just done it. Thanks for the "heads-up" ;-)
