[PATCH] powerpc: dts: fsl: Drop unused .dtsi files

[PATCH] powerpc: dts: fsl: Drop unused .dtsi files

[Rob Herring (Arm)]

These files are not included by anything and therefore don't get built or
tested.

There's also no upstream driver for the interlaken-lac stuff.

Those two files were added by commit 8c43d2b0ca10 ("powerpc: Add T4 LAC 
device tree binding & defs") together with 
Documentation/devicetree/bindings/powerpc/fsl/interlaken-lac.txt

Should the Documentation file be removed as well ?

Regardless,

Yes, once there is no user, I will remove the binding.
