Hello everyone,
This patchset adds support for fwnode to V4L2. Besides OF, also ACPI based
systems can be supported this way. By using V4L2 fwnode, the individual
drivers do not need to be aware of the underlying firmware implementation.
The patchset also removes specific V4L2 OF support and converts the
affected drivers to use V4L2 fwnode.
The patchset depends on another patchset here:
<URL:http://www.spinics.net/lists/linux-acpi/msg72973.html>
v1 of the set can be found here:
<URL:http://www.spinics.net/lists/linux-media/msg111073.html>
changes since v1:
- Use existing dev_fwnode() instead of device_fwnode_handle() added by the
ACPI graph patchset,
- Fix too long line of ^'s in ReST documentation.

Pass the more generic fwnode_handle to the init function than the
device_node.

The fwnode_handle is a more generic way than OF device_node to describe
firmware nodes. Instead of the OF API, use more generic fwnode API to
obtain the same information.
As the V4L2 fwnode support will be required by a small minority of e.g.
ACPI based systems (the same might actually go for OF), make this a module
instead of embedding it in the videodev module.

Add fwnode matching to complement OF node matching. And fwnode may also be
an OF node.

OF and fwnode support are separated in V4L2 and individual drivers may
implement one of them. Sub-devices do not match with a notifier
expecting sub-devices with fwnodes, nor the other way around.
Fix this by checking for sub-device's of_node field in fwnode match and
fwnode field in OF match.

Switch users of the v4l2_of_ APIs to the more generic v4l2_fwnode_ APIs.
Existing OF matching continues to be supported. omap3isp and smiapp
drivers are converted to fwnode matching as well.

Instead of including the V4L2 OF header in ReST documentation, use the
V4L2 fwnode header instead.

To: linux-media; +Cc: linux-acpi, devicetree, laurent.pinchart
Pass the more generic fwnode_handle to the init function than the
device_node.
