Subject: [PATCH v2 0/3] dmaengine/ARM: sprd: use proper 'dma-channels/requests' properties

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.

The patchset is bisectable - please pick up through independent trees.

Changes since v2
================
1. Keep old properties, so the patchset is bisectable.
2. Add review tags.

Best regards,
Krzysztof
