This patch fixes problems(kernel oopses) with unplug of device while
it's working.
Patch adds disconnect_lock mutex, changes usb_amradio_close and
usb_amradio_disconnect functions and adds a lot of safety checks.

file read failure
If APU firmware file read failed, the jump vector to the APU was undefined and
the APU would be started executing garbage. Fix uninitialized variable to be
an infinite loop for the APU, but also bail out before even starting the APU.

interrupts to driver
When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for. This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver. This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.

All waits for cx18 mailbox API commands are now uninterruptable. Added
code to collect mailbox ack statistics. Tweaked timeouts based on collected
stats and video vertical frame and field rates.

cx18: Improve handling of outgoing mailboxes detected to be busy. When
encountering a busy mailbox, sleep instead of polling, and wait for interrupt or
timeout. If the mailbox is still busy, force it free. When sending commands,
make sure we never create a situation where we mark the mailbox busy upon
sending, and ensure we always have a method to cleanly recover from a busy
mailbox.

waitq vs poll
Add mutexes to ensure exclusive access for outgoing driver to CX23418 mailboxes.
Also wait on a waitq for mailbox acknowledgement from the CX23418 instead of
polling.

work handler
cx18: Use default kernel work queue; fix streaming flag for work handler.
Eliminate cx18 specific work queue and use the kernel default work queue.
Fixed the F_STREAMING_FLAG for the TS stream so cx18_dvb_work_handler()
can know when it is not safe to send MDLs to the firmware.

cx18: Reduce number of mmio read retries to improve performance. Experiments
have shown 2 things: read retries never improve the result of a suspect mmio
read from the CX23418 (the result stays all 0xff's), and that most of the
suspected read failures are actually proper reads of values that should be
all 0xff's. This change reduces the number of read retries and keeps the
count separate from write retries.

Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
incoming symbols and hence might run into problems at the very end of the
specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
running at 90MHz, raises lot of issues such as the need to recalculate
all of them , which is eventually very painful.

Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg()
used to setup register names by em28xx_write_reg().
Also, documents the register names that are known.
This patch were generated by this small perl script:
my %reg_map = (
# Register table - the same as defined on parse_em28xx.pl script
);
while (<>) {
if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
my $reg = $2;
my $val = $3;
$val =~ tr/A-f/a-f/;
$reg = $reg_map{$reg} if defined($reg_map{$reg});
printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
} elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
my $reg = $2;
my $val = $3;
$val =~ tr/A-f/a-f/;
$reg = $reg_map{$reg} if defined($reg_map{$reg});
printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;

Several fields are duplicated on both structs. Let's just copy em28xx_board instead.
A later cleanup could just copy the fields that are changed, in order to keep em28xx_board
const.

Remove unused em28xx_board.vchannels and em28xx.video_channels.
Also, .is_em2800 = 0 is not needed, as all data is zeroed by kernel loader.
The table also included a notice that svideo weren't test on Hauppauge
USB2. Remove this notice, since this input also works properly.
Also, it does some whitespace cleanups.

The previous patches removed XCLK and I2C magic. Now, we finally know
what those registers do. Also, only a very few cards need different
setups for those.
Instead of keeping the setups for those values inside the per-device
hack magic switch, move the uncommon values to the board-specific
struct, and have a common setup for all other boards.
So, almost 100 lines of hacking magic were removed.
A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk
were set, without taking any care about not overriding a previous xclk setup.

The OmniVision OV534 is the USB bridge chip used in Sony Playstation EYE,
it is found also in other webcams like Hercules Blog Webcam and
Hercules Dualpix HD.
This driver is the port to gspca of a prototype driver by Mark Ferrell
based on vivi. The original code to initialize the camera and start the
capture is from Jim Paris on ps2dev.org, here integrated with the analysis
of the USB communications taken by the windows driver.
