Hi,

The core DT schema defines generic 'dma-channels' and 'dma-requests'
properties, so in preparation to moving bindings to DT schema, convert
existing users of '#dma-channels' and '#dma-requests' to the generic
variant.

Not tested on hardware.

IMPORTANT
=========
The patchset is not bisectable! The DTS patches should be applied a
release *after* driver change is accepted.

Best regards,
Krzysztof

There's no driver change though...

Indeed, copy paste cover letter. This FSL dma driver does not use the
properties, so it's only in the bindings and in the DTS. The patchset
can be taken as-is, without in-kernel ABI break. Only out-of-tree
users of DTSI will be affected.

Best regards,
Krzysztof
