From: Songjun Wu <[email protected]> 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.
Signed-off-by: Songjun Wu <[email protected]> [[email protected]: split and adapt to newer kernel] Signed-off-by: Nicolas Ferre <[email protected]> --- 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.
