Introduce bus_flags to specify display bus properties like signal polarities. This is useful for parallel display buses, e.g. to specify the pixel clock or data enable polarity.

In case this wasn't clear: That ack is good enough to just smash this patch into your fsl-dcu tree and send a pull request to Dave for it. No need to resend the patches. Just mention in the pull that you have stuff included outside of your driver, and that it's all acked. -Daniel
I almost suspected it, but was not sure whether that would be ok. Thanks for the clarification.
Will create a pull request today.
