Should we start directly with 0 and 1 postfix ?What are the differences exactly without the two mixers? I was hoping to be able to cover them all using properties, indices are usually pretty badly received in compatibles.1. VEP is only available on the VI channel in mixer0. (VEP may mean Video Enhance Processor) 2. Smart Backlight is only available in mixer0's on SoCs with LCD. 3. Writeback function is only available in mixer0.
Then yeah, we can totally support that using properties.
