The code of the dvb-pll driver and the lgh06xf driver is nearly
identical. The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call. The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it. By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.
There is one other difference. dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this. In some devices the PLL is not reachable over I2C at the timer the
tuner is attached. Some more initialization, such as firmware loading,
must take place first. None of the devices using a LG-H06xF should have
this problem.

The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly. To work around
this, makefiles would define some new macro based on the setting of a
config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary. This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such. Officially export them.
VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h
to videodev2.h.
Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be
duplicated in each driver's call-back function. CAP_SYS_ADMIN check is
added to pvrusb2 (which doesn't use video_ioctl2).

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

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.

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.

Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
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.

i2c-algo-bit: Discard the mdelay data struct member
The i2c_algo_bit_data structure has an mdelay member, which is not
used by the algorithm code (the code has always been ifdef'd out.)
Let's discard it to save some code and memory.

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.

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.

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.

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.

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)

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.

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.

Use release_firmware() to free requested resources.
According to Documentation/firmware_class/README the request_firmware()
call should be followed by a release_firmware(). Some drivers do not
however free the firmware previously allocated with request_firmware().
