Mauro Carvalho Chehab 2e5ef2dfc4 V4L/DVB (9980): em28xx: simplify analog logic
Now, just two routines are enough for analog: the first one configs the analog
part and register V4L2 devices, and the second one release analog devices.

After this patch, it will be easier to transform em28xx-video into an em28xx
extension, loaded only on analog devices.

Mauro Carvalho Chehab 1a23f81b7d V4L/DVB (9979): em28xx: move usb probe code to a proper place
em28xx-video were holding several code that are not specific to V4L2
interface.

This patch moves the core code for em28xx-core, and usb probing code
into em28xx-cards.

This opens the possibility of breaking em28xx into a core module and a
V4L2 module, loaded only on devices that have analog interfaces.

Some cleanup may be done at em28xx-cards to optimize the config code.

Drivers that use v4l2_device can set that as parent pointer in the v4l2_dev
field instead of using the struct device parent field.

This allows v4l2-dev.c to check whether this driver is v4l2_device based,
and if so then it can offer additional services.

Hans Verkuil dc93a70cc7 V4L/DVB (9973): v4l2-dev: use the release callback from device instead of cdev
Instead of relying on the cdev release callback we should rely on the
release callback from the device struct. This requires that we use
get_device/put_device to do proper refcounting. In order to do this
safely v4l2-dev.c now sets up its own file_operations that call
out to the driver's ops.

Use a consistent crystal value of 28.636360 MHz for computing all PLL
parameters so clocks don't have relative error due to assumed crystal
value mismatches.  Also aimed to have all PLLs run their VOCs at close to
400 MHz to minimze the error of these PLLs as frequency synthesizers. Also
set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware
are loaded.  Also fixed I2S Master clock dividers.

Many thanks to Mike Bradley and Jeff Campbell for reporting this problem and
suggesting the solution, researching and experimenting, and performing
extensive testing to support their suggested solution.

data from the camera matches the UVC payload format.  This lets us
better reassemble the data into frames and know when data was lost.

This also lets us relax the bulk_size requirement from 600K to 2K,
which should help systems on with limited RAM (like the PS3).

This is a port of the fixes Hans Verkuil made for ivtv/cx25840:
The service_set field was used to determine whether raw or sliced VBI was
desired. This is incorrect since it is perfectly valid to select sliced VBI
with a service_set of 0.

Instead the driver should check on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.

Updated the cx18 driver accordingly, including an additional check in
cx18_start_v4l2_encode_stream() that didn't exist in ivtv.

Julia Lawall a8782f669c V4L/DVB (9796): drivers/media/video/cx88/cx88-alsa.c: Adjust error-handling code
In the function cx88_audio_initdev, the value card has been created using
snd_card_new.  The other error handling code in this function frees the
value using snd_card_free.  I have thus changed the first error case to do
the same.  On the other hand, it may be that card is not sufficiently
initialized at this point to use snd_card_free, in which case something
else should be done to free the memory in the error case.

In the function snd_cx88_create the call kfree(chip) in one error case
looks suspicious, both because it is not done in the other error code, and
because chip points into the middle of the memory allocated by
snd_card_new, ie it is not itself associated with a separate kmalloc.
Therefore I have removed it.

The semantic match that finds the first problem is as follows:

Pixel format requested by the user is not necessarily the same, as what
a sensor driver provides. There are situations, when a camera host driver
provides the required format, but requires a different format from the
sensor. Further, the list of formats, supported by sensors is pretty static
and can be pretty good described with a constant list of structures. Whereas
decisions, made by camera host drivers to support requested formats can be
quite complex, therefore it is better to let the host driver do the work.

Probably due to a removed code, tda827x were doing some wrong calculus at the
returned frequency. I suspect that the original idea were to return the
programmed divisor converted into frequency again.

However, the current code is sometimes multiplying the programmed frequency by
62500, and, on other cases, like radio, it dividing it by 1000.

Instead of doing such math, let's just store the frequency value as requested by
the caller module.

em28xx devices generally get hot when xc3028 tuner is powered on. This
patch solves this by turning power off when the device is not used, at the

A major rewrite of interrupt handling for incoming mailbox processing, to split

Setup a pool of work "order forms" for the irq handler to send jobs to the new
work handler routine which uses the kernel default work queue to do the
deferrable work.  Started optimizing some of the cx18-io calls as they are now
the low hanging fruit for recoving microseconds back from the timeline.
Future optimizations will get rid of mmio read retries, mmio stats logging, and
combine smaller functions in the irq path into the larger ones to save ~2 us
each.

Mauro Carvalho Chehab d4d889e329 V4L/DVB (9751): em28xx: card description cleanups
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.

Mauro Carvalho Chehab a2070c6654 V4L/DVB (9747): em28xx: Properly handles XCLK and I2C speed
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.
