Merge tag 'omapdss-for-3.11-2' of git://gitorious.org/linux-omap-dss2/linux into fbdev/for-next 

OMAP display subsystem changes for 3.11 (part 2/2)

This is the second part of OMAP DSS changes for 3.11. This part contains the
new DSS device model support.

The current OMAP panel drivers use a custom DSS bus, and there's a hard limit
of one external display block per video pipeline. In the new DSS device model
the devices/drivers are made according to the control bus of the display block,
usually platform, i2c or spi. The display blocks can also be chained so that we
can have separate drivers for setups with both external encoder and panel.

To allow the current board files, which use the old style panels, to function,
the old display drivers are left in their current state, and new ones are added
to drivers/video/omap2/displays-new/. When the board files have been converted
to use the new style panels, we can remove the old code. This is planned to
happen in v3.12.

Having to support two very different DSS device models makes the driver
somewhat confusing in some parts, and prevents us from properly cleaning up
some other parts. These cleanups will be done when the old code is removed.

The new device model is designed with CDF (Common Display Framework) in mind.
While CDF is still under work, the new DSS device model should be much more
similar to CDF's model than the old device model, which should make the
eventual conversion to CDF much easier.
