[PATCH v4 4/6] ARM: davinci: da8xx: add pdata-quirks for VPIF capture

From: Bartosz Golaszewski
Date: Tue Feb 28 2017 - 12:48:24 EST


From: Kevin Hilman <khilman@xxxxxxxxxxxx>

For da8xx DT platforms, use pdata-quirks to add legacy platform data for
vpif_capture driver.

Passing legacy platform_data is required until the V4L2 framework, and
subdevice drivers (such as the tvp514x) grow a way of selecting input
and output routing (c.f. V4L2 s_routing API)

Signed-off-by: Kevin Hilman <khilman@xxxxxxxxxxxx>
[Bartosz:
- removed unnecessary #ifdefs
- split the init function into two separate routines for the lcdk
and evm boards]
