This patch series which incorporates changes in DSS2 to enable
omap_dss_device instances to use the new Overlay Manager LCD2 in
DISPC.
On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. This
channel's video port is a source port for RFBI, DSI2 and DPI. The
Primary channel's video port is connected to RFBI and DSI1.
There is a set of regsiters for LCD2 channel similar to the existing
LCD channel, like DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so
on.
In order to decide which LCD Overlay Manager to configure(LCD/LCD2),
there is a need for the omap_dss_device instances to tell the interface
drivers(DSI, DPI, RFBI etc) which LCD channel they want to connect to, so
that the corresponding registers get configured. Therefore, a new
enum omap_channel member is introduced to omap_dss_device.
This design was made keeping in mind the possible addition of more
Overlay Managers in future OMAPs, this code is also backward compatible
with OMAP3 as omap_dss_device instances in OMAP3 will stick only with
OMAP_DSS_CHANNEL_LCD.

argument

Version 5:
- Replaced dssdev->channel with dssdev->manager->id in interface driver
calls, dssdev->channel is only used once in dss_recheck_connections()
to set up the connection between panel device and dispc managers
- DISPC_CONTROL and DISPC_CONFIG registers are not defined with channel
as a parameter.
Version 4:
- Broken into smaller patches in order to build in between patches.
- Some basic cleanup
Version 3:
- Patches are reworked over dss2 features framework. Number of patches
are reduced.
Version 2:
- The DISPC_BASE macro now isn't changed for OMAP4, a future
hwmod patch will take care of this dynamically.
- Supported_displays member of manager is now assigned correctly
for OMAP2.
- DISPC Registers common to LCD and LCD2 channels are not defined
separately, now there is a parameter which differentiates between
the 2 channels.
- Secondary LCD manager is now named as lcd2 instead of 2lcd, the
patch given in the link below allows DSS2 interpret this correctly.
