[PATCH 1/2] ARM: dts: at91: sama5d2: add classD node

From: Songjun Wu <redacted>

Add Class D audio amplifier node to sama5d2 description. The binding
documentation is already accepted and included as
Documentation/devicetree/bindings/sound/atmel-classd.txt.

Hi,

Note that this node needs the audio PLL clock which is not submitted yet. So,
this series can't be applied right now: we have to wait for the audio PLL
driver and binding to be accepted and included first.

I send it right now so that it's not forgotten and easyer to track. Moreover,
the binding won't certainly change.

Bye,
