Merge tag 'davinci-for-v4.12/soc' of git://git.kernel.org/pub/scm/lin…

…ux/kernel/git/nsekhar/linux-davinci into next/soc

Pull "DaVinci SoC updates for v4.12" from Sekhar Nori:

v4.12 SoC updates for DaVinci include necessary pdata-quirks
to make video capture and display work on da850.

VPIF driver which supports video capture and display on
da850 is a legacy driver.  It does not have DT equavalents
for all things that are used on platform data.

Attempts were made to pass data via DT[1], but linux-media
does not yet have a good way of describing subdevices in
device tree. This is work in progress. As soon as bindings
are defined and implementation is available, we can shift
to using that. For now we are stuck with using pdata.

The pull request also has some clean-up for PM, and a fix
for pdata quirks mechanism.
