Currently, webcam support works only at RGB565, at 640x480.

This webcam uses a em2710 chipset, that identifies itself as em2820,
plus a mt9v011 sensor, and a DY-301P lens.
It needs a few different initializations than a normal em28xx device.
Thanks to Hans de Goede <hdegoede@redhat.com> and Douglas Landgraf
<dougsland@redhat.com> for providing the acces for the webcam during
this weekend, I could make a patch for it while returning back from
FISL/Fudcom LATAM 2009.

The original driver for Silvercrest cameras were using some values that
are different from what datasheet says. As result, it was taken very
less snapshots per second than expected.
A test with the datasheet values showed that they work fine and give a
better frame rate. So, let's stick with datasheet values.

Instead of working with a table of precalculated values, fill them with
the proper values. Also, adds format functions that allow changing the
resolution, by cropping the image to the center of the sensor.
While here, move the sensor version check to the probe routine, to
indicate to the caller if the sensor is not supported by this driver.
Also, fixes a stupid bug where we're using &buffer[] instead of
buffer[].

Add DVB-T support for Yuan MPC-718 cards with an MT352 or ZL10353 demodulator.
There are apparently some units with a DiBcom demodulator which could be
supported by one of the dib7000 modules - but this is not implemented in the
cx18 driver (yet).
Due to lack of porgramming details for the MT352 and the mt352 module requiring
a "demod_init" function, a "firmware" must be obtained and loaded to get
DVB-T working for Yuan MPC-718 cards with an MT352.

precalculate_bars() improved vivi performance. However, it assumed that
always before streaming, the driver would call VIDIOC_S_STD. This is not
an API requirement, and the testing apps don't do that.
Due to that, a regression were caused by the patch that added it.
This patch moves the precalculate_bars to the proper place of the code,
calling it at buffer_prepare() callback.

Commit 537a1bf059 (fbdev: add mutex for
fb_mmap locking) introduces a ->mm_lock mutex for protecting smem
assignments. Unfortunately in the case of sm501fb these happen quite
early in the initialization code, well before the mutex_init() that takes
place in register_framebuffer(), leading to:
Badness at kernel/mutex.c:207

The current ssb irq setup in ssb_mipscore_init has the problem that it
configures some device on some irq without checking that the irq is not
taken by an other device.
For example in my case PCI host is on irq 0 and IPSEC on irq 3.
The current code:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host
But now IPSEC irq is not routed anymore to the mips code and dev->irq is
wrong. This causes a problem described in [1].
This patch tries to solve the problem by making set_irq configure the
device we want to take the irq on the shared irq0. The previous example
becomes:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host:
- irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
I also added some code to print the irq configuration after irq setup to
allow easier debugging. And I add extra checking in ssb_mips_irq to report
device without irq or device with not routed irq.

and pci_bus_assign_resources() in the opposite order from everyone else.
No reason and I couldn't see any data dependency.
Patch below applies cleanly to 2.6.30-rc2.
Later, I suspected the code worked only because no drivers would be
loaded/ready until much later in the system initialization sequence.
Tested "LBA" code on J6000 (32-bit) and A500 (64-bit SMP) with 2.6.30-rc2.
