New interface is proposed for dither functionality. This future allows composing an external signals to the selected output channel. The dither signal can be turned on/off, scaled, inverted, or it can be selected from different sources. Signed-off-by: Cristian Pop <redacted>
Hi Cristian, One trivial inline to fix if you need to respin. Otherwise I can tidy up whilst applying. Jonathan

Typo, enable but I can fix that whilst applying if there is nothing else. Jonathan
