Subject: [PATCH v2 0/9] ARM/arm64: dts: drop useless 'dma-channels/requests' properties

Hi,

Changes since v1
================
1. After discussion with Marek and Rob, drop the properties entirely instead of
   fixing the names.
2. Not adding acquired review tags because of that change.
3. Drop mfd patch (applied).

Description
===========
Rob reported [1] that many (all?) PL330 device nodes use wrong dma-channels and
dma-requests properties.  The proper ones are without leading '#'.

I guess everything started with 42cf20980cde ("ARM: dts: pl330: Add #dma-cells for
generic dma binding support").

Patches are independent and can be picked-up as is. Otherwise please ack and
I'll push it to SoC.

Krzysztof
