Well, I don't understand completely. Since our discussion during 3.10
merge window ([GIT PULL] at91: DT changes for 3.10 #2), I try to conform
to this rule:

1/ all pre-3.10 and 3.10 device tree file names stay unchanged
-> sama5d3.dti (SoC)
-> sama5d35ek.dts (board)

2/ all *SoC* DT files conform to their marking:
at91sam9263.dtsi
at91sam9rl.dtsi
sama5d3.dtsi, sama5d36.dtsi
sama5d4.dtsi, sama5d46.dtsi (maybe in the future, who knows...)

3/ all post-3.10 *boards* have the "at91-" prefix, whether they are
populated with sam9 or sama5:
at91-ariag25.dts (since 3.10, using a at91sam9g25)
at91-qil_a9260.dts (since 3.14, using at91sam9260)
at91-sama5d3_xplained.dts (since 3.14, using sama5d36)

The rule for AT91 has never been to prefix the board DT filename with
the name of the SoC or SoC family.

Well, I do not know what to fix as the files were already present in
mainline before this kernel revision and that I am a little bit
reluctant to change file names after they are merged in mainline.

Now, can we keep the current policy described above (somehow weird, I
admit) for future SoCs and boards?

Best regards,
