Cover letter [RFC PATCH 0/6] media: davinci: VPIF: add DT support
Quoted 7 lines · Kevin Hilman

This series attempts to add DT support to the davinci VPIF capture driver.

I'm not sure I've completely grasped the proper use of the ports and endpoints stuff, so this RFC is primarily to get input on whether I'm on the right track.

Quoted 7 lines

The last patch is the one where all my questions are, the rest are just prep work to ge there.

Tested on da850-lcdk and was able to do basic frame capture from the composite input.

Series applies on v4.9-rc1

And FYI for anyone wanting to test, it needs a few config options enabled[1] that are not (yet) part of davinci_all_defconfig. I'll update the defconfig when I'm ready to send non-RFC patches.
