Add the code to make the DSI driver work with device tree on OMAP3 and
OMAP4.

A minor hack is needed at the moment in the DSI driver: the DSS driver
needs to know the ID number of a DSI device, as clocks are routed in
different ways to the DSI devices. At the moment we don't have any
proper way to manage this, so this patchs adds a simple lookup table
that is used to deduce the ID from the DSI device's base address.

Add DT support for DSS. Contrary to the non-DT version, the DSS in DT
mode contains DPI and SDI outputs, which better reflects the hardware.
The non-DT code will be removed after all boards have been converted to
DT, so there's no need to change the non-DT code to act the same way.

The code for DPI and SDI needs to be refined later to make it possible
to add multiple DPI ports. For now, handling just a single DPI port is
enough for all the boards.

The regulator names used for DSS components are somewhat ugly for DT
use. As we're just adding DT support, it's simple to change the
regulator names.

This patch makes the DSS driver get the regulators with somewhat cleaner
names when bootin with DT. For example, this allows us to define HDMI's
VDDA regulator in the DT data as:

vdda-supply = <...>;

instead of

vdda_hdmi_dac-supply = <...>;

Add helpers to get ports and endpoints from DT data.

These helpers parse v4l2 style ports and endpoints, but compared to the

We currently create a "displayX" style alias name for all displays,
using a number that is incremented for each registered display. With the
new DSS device model there is no clear order in which the displays are
registered, and thus the numbering is somewhat random.

This patch improves the behavior for DT case so that if the displays
have been assigned DT aliases, those aliases will be used as DSS
aliases.

This means that "display0" is always the one specified in the DT alias,
and thus display0 can be used as default display in case the user didn't
specify a default display.

As there is no common panel framework in the kernel, we have OMAP
specific panel drivers. However, the DT data should be generic. This
brings the issue that some other platform could use the same panels, and
would need to create a driver with the same 'compatible' string as the
OMAP driver.

In the long run, we have to get a common panel framework. For the time
being, this patch solves the issue:

At early boot time, we go through the DT nodes looking for the panels
the kernel supports for OMAP. For each found node, the 'compatible'
string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes
"omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss,"
at the beginning of their compatible field.

This allows us to have generic DT data, but OMAP specific display
drivers.
