1c5ee876d6 V4L/DVB (4938): Cx88: Convert lgdt3302 tuning function to use dvb_pll_attach
There was a still a pre-dvb-pll set_params function for the lgdt3302 in
the cx88-dvb driver.  This patch removes that function and uses
dvb_pll_attach() for the cards that were using it (Dvico FusionHDTV 3
GOLD {Q,T}).  This way the set_params function from dvb-pll is used.
dvb_attach() is in turn used on dvb_pll_attach(), eliminating some static
dependencies on dvb-pll.  There are still a couple static dependencies on
dvb-pll remaining.

76db93d03f V4L/DVB (4846): Create new lgh06xf atsc tuner module
This patch creates a new atsc tuner module for the LG TDVS-H06xF ATSC tuners,
called lgh06xf.  The purpose of this change is to reduce some duplicated
code, and to allow the lgh06xf tuner code to take advantage of dvb_attach().
As a side effect, the dependency of dvb-bt8xx on dvb-pll has been removed,
since the lgh06xf module itself will use dvb-pll, while remaining optional
for the dvb-bt8xx driver through the use of DVB_FE_CUSTOMISE

6c5be74c86 V4L/DVB (4676): Dynamic cx88 mpeg port management for HVR1300 MPEG2/DVB-T support.
A series of patches to change the cx88 framework to allow the
PCI mpeg port to be shared dynamically between different
types of drivers or applications. This patch changes the cx88-dvb
and cx88-blackbird drivers to become 'sub drivers' of a higher
single cx88-mpeg driver.
The cx88-mpeg driver is a superset of the previous cx88-mpeg/blackbird
drivers and now owns the IRQ. cx88-dvb/blackbird now become mini drivers,
registering themselves with cx88-mpeg through a standard interface with
callbacks.
Sub drivers request access to hardware via the cx88-mpeg driver. In turn
the cx88-mpeg driver determines whether the hardware is busy and accepts
or refuses the request, grant access using callbacks into the sub drivers.
The net effect is that you are no longer able to tamper with the mpeg port
from multiple different applications at the same time, potentially breaking
a live mpeg2 hardware encoding or dvb stream.
The mechanism extends to enable multiple dvb frontends to be registered
and share the single resource.

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

4f43ac0cb2 V4L/DVB (4681): Cx88: fix analog capture notch filter
This patch changes the setting of the cx2388x notch filter to match that of
the video capture sample frequency, removing some annoying interference
lines THAT would appear when capturing composite video. This has been tested
in PAL and NTSC TV norms.
It sets the Y/C separation luma notch filter, which removes the chroma signal
from the luma signal when using a composite input.
The luma notch filter operates at the video decoder's frequency, not the ADC's
frequency or at the frequency of the scaled video. Y/C separation happens after
the sample rate converter, before video scaling.
The datasheet provides plots of the filter response for three _video decoder_
frequencies, 4x Fsc, square pixel, and ccir601.  These are the same three
frequencies for the notch filter control.  It seems pretty clear that this
filter should be set based on the video decoder frequency. The cx88 driver
always uses a video decoder frequency of 4xFsc.

aa481a6547 V4L/DVB (4638): Basic DVB-T and analog TV support for the HVR1300.
This is the first in a series of patches to add full WinTV-HVR1300
support to Linux. This first patch will enable analog TV support
and DVB-T support. Later patches will add the hardware MPEG encoder
support.

141276b57e V4L/DVB (4609): Improved i2c performance on software bitbang algoritm
Software I2C were using a very conservative value of udelay=16, meaning about
20Kbps. According with Philips I2C datasheet, the i2c should answer well for
times at the order of 4.7 us. So, using udelay=5 should work for all devices.
After this patch, the speed should be close to 66,67 Kbps, with the current
kernel software bitbang, with 30/60 duty cycle.
Anyway, added a new parameter (i2c_udelay) that would allow using conservative
values, if eventually a hardware doesn't support the datasheet values.
Thanks to Jean Delvare <khali@linux-fr.org> for pointing this improvement.

3153d0d05d V4L/DVB (4509): Added missing copyright
Several changes at register stuff were done since commit
b45009b028, but I've forgot
to add the copyright line for this. Those changes allowed
cx88 to have multiple tuners, allowing it to support hardware with
separated radio and video tuners. It also allows binding a tuner to an
specific i2c address.

e738e35d1e V4L/DVB (4504): Enable audio DMA restart on channel change even when cx88-alsa is compiled
cx88-alsa can be compiled in (in distro built kernels, for example), but
not used. In those cases, the audio DMA restart is needed for proper sound
on NICAM channels.
This patch enables the DMA restart even with ALSA, but the functions now
check if cx88-alsa is really active.

d536e9c41f V4L/DVB (4497): Reset USB part of DViCO Dual Digital during PCI driver attach
If the FX2 does not reset properly during reboot, it can present an
invalid USB device ID and fail to attach.  Prevent this situation
from occuring by resetting the USB part of the card when the PCI part
probes.
Also fix the GPIO configurations so that analog capture will not
inadvertantly reset the USB part.

ef76856d26 V4L/DVB (4479): LNB voltage control was inverted for the benefit of geniatech cards on Kworld
1) It sets LNBDCPol differently based on the card type. Now it should
work properly for both the kworld and geniatech cards.
2) It stops returning an error for the SEC_VOLTAGE_OFF voltage command
(the cx88-dvb level handles the actual voltage on/off, but it still
passes the ioctl down to the cx24123 level, which previously rejected
the OFF as invalid so the ioctl would report failure)

4ad8eee5ac V4L/DVB (4438): Fix dvb_pll_attach for nxt2004-based cards
The test in dvb-pll to see if a tuner's PLL responds when attaching fails
on NXT2004 based boards before the firmware is loaded.
This patch allows us to avoid this test by not passing an I2C bus handle to
the dvb_pll_attach routine, just as Chris Pascoe has done for MT352 and
ZL10353 based boards when used in cx88-dvb.

c162dff643 V4L/DVB (4436): Dvb-pll support for MT352/ZL10353 based tuners.
Typical wiring of MT352 and ZL10353 based tuners differs from dvb-pll's
expectation that the PLL is directly accessible.  On these boards, the
PLL is actually hidden behind the demodulator, and as such can only be
accessed via the demodulator's interface.  It was failing to communicate
with the PLL during an attach test and subsequently not connecting the
tuner ops.
By passing a NULL I2C bus handle to dvb_pll_attach, this accessibility
check can be bypassed.  Do this for the affected boards.  Also fix a
possible NULL dereference at sleep time, which would otherwise be
exposed by this change.
