There is no limit to the number of displays that can registered with DSS2. The
current value of MAX_DISPLAYS is 3, set this to 10 so that the 'displays'
member of omap2video_device struct can store more omap_dss_device pointers.

This fixes a crash seen in omap_vout_probe when DSS2 registers for more than 3
displays.

Add support for DSI panels. DSI video mode panels will work directly. For
command mode panels, we will need to trigger updates regularly. This isn't done
by the omap_vout driver currently. It can still be supported if we connect a
framebuffer device to the panel and configure it in auto update mode.

Currently, in omap_vout_isr(), if the panel type is DPI, and if we
get either VSYNC or VSYNC2 interrupts, we proceed ahead to set the
current buffers state to VIDEOBUF_DONE and prepare to display the
next frame in the queue.

On OMAP4, because we have 2 LCD managers, the panel type itself is not
sufficient to tell if we have received the correct irq, i.e, we shouldn't
proceed ahead if we get a VSYNC interrupt for LCD2 manager, or a VSYNC2
interrupt for LCD manager.

Fix this by correlating LCD manager to VSYNC interrupt and LCD2 manager
to VSYNC2 interrupt.

The commit 383e4f69 makes reqbuf prevent
requesting a larger size buffer than what is allocated at kernel boot during
omap_vout_probe.

In omap_vout_buffer_setup callback API, the requested size is compared with
vout->buffer_size, this isn't correct as vout->buffer_size is later set to the
size requested in reqbuf. When the video device is opened the next time, this
check will prevent us to allocate a buffer which is larger than what we requested
the last time.

Don't use vout->buffer_size, always check with the parameters video1_bufsize
or video2_bufsize.

If "i" is 2 then when we call cx25821_video_mux() we'd end up going
past the end of the cx25821_boards[dev->board]->input[].

The INPUT() macro obfuscates what's going on in that function so it's
a bit hard to follow.  And as Mauro points out the hard coded 2 is
not very helpful.

The Kconfig symbol RADIO_TEA5764_XTAL is unused. The code does use a
RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems
to be a way to keep both. (The easiest way out would be to rip out both
the Kconfig symbol and the macro.)

Note there's also a module parameter 'use_xtal' to influence all this.

The most important change in this patch is direct linking to struct
soc_camera_link via the client->dev.platform_data pointer. This makes most
of the soc-camera client drivers also usable outside of the soc-camera
framework. After this change all what is needed for these drivers to
function are inclusions of soc-camera headers for some convenience macros,
suitably configured platform data, which is anyway always required, and
loaded soc-camera core module for library functions. If desired, these
library functions can be made generic in the future and moved to a more
neutral location.

The only two client drivers, that still depend on soc-camera are:

mt9t031: it uses struct video_device for its PM. Since no hardware is
available, alternative methods cannot be tested.

ov6650: it uses struct soc_camera_device to pass its sense data back to
the bridge driver. A generic v4l2-subdevice approach should be developed
to perform this.

VIDIOC_G_STD can return the current TV-norm to the user in one of two ways:
if an .vidioc_g_std() ioctl operation is provided by the driver, it is
called, otherwise the value ot the .current_norm field of struct
video_device is returned. Since subdevice drivers currently have no access
to struct video_device objects, the only way to provide this information to
the user is by implementing a .g_std() method.
