This series adds pdata quirks and other changes required to make vpif work on the da850-evm board. v1 -> v2: - added patch 1/5 - don't bail-out from pdata_quirks_check() after applying a single quirk - changed the comment above the new fixed regulator to make it more descriptive - removed unnecessary #ifdefs from pdata-quirks.c Bartosz Golaszewski (3): ARM: davinci: da8xx: allow having multiple pdata-quirks ARM: da850-evm: add a fixed regulator for the UI board IO expander ARM: davinci: add pdata-quirks for da850-evm vpif display Kevin Hilman (2): ARM: davinci: board-da850-evm: add I2C ID for VPIF ARM: davinci: da8xx: add pdata-quirks for VPIF capture arch/arm/mach-davinci/board-da850-evm.c | 4 + arch/arm/mach-davinci/da8xx-dt.c | 1 + arch/arm/mach-davinci/pdata-quirks.c | 171 +++++++++++++++++++++++++++++++- 3 files changed, 175 insertions(+), 1 deletion(-) -- 2.9.3

Similarly to vpif capture: we need to register the vpif display driver
and the corresponding adv7343 encoder in pdata-quirks as the DT
support is not complete - there isn't currently a way to define the
output_routing in the V4L2 drivers (c.f. s_routing) via DT.

| Subject | [PATCH v2 3/5] ARM: davinci: da8xx: add pdata-quirks for VPIF capture |
| Message-ID | <tdl19-4zS-37@gated-at.bofh.it> |
| In reply to | #1585456 |
From: Kevin Hilman <khilman@baylibre.com>
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)
