[PATCH v2 0/2] [media] s5p-tv: Add initial DT-support to s5p-tv's subdevices

[Karol Lewandowski]

Changes since v1:
 - dropped patch for sii9234 driver - driver itself hasn't been merged yet
 - changed compatible string to name first known SoC having given features
   (IP blocks, actually) [Thanks Thomas!]


This patchset adds initial device tree support to drivers used by
s5p-tv on Exynos4.

DT support for s5p-tv driver itself would benefit from changes to v4l
core (missing OF helper functions) and thus, will be sent later in
separate patchset.

Need to add this new compatible string to
Documentation/devicetree/bindings.

Otherwise looks good.

Ditto here; needs to be listed in documentation.

As these drivers require only irq and io address may add these to
something like [bindings/arm/samsung/]trivial-devices.txt (like it's
done for i2c)?

Thanks for review!

yes.  I just want the values in the documentation where they can be
searched for.
