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.

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.

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.

55d81aa5c1 V4L/DVB (9937): cx18: Use a consistent crystal value for computing all PLL parameters
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.

Tuning to a weaker channel shows that the hardware recovers sync:

Also, tuning, moving the dish and then restoring the dish also retunes.

2fac9a0f44 V4L/DVB (9916): dvb-core: don't add an event when in ONE SHOT mode for algo type HW
It has been noticed that in HW tuning mode in cx24123.c that
a check is made to not alter the status var when in one shot
mode, a simpler solution is to not update here for all cards.

e278e746bc V4L/DVB (9913): tuner-xc2028: allow printing stack trace as debug on sleep code
tuner-xc3028 can be put to sleep to save power. However, if not properly
recovered from sleep, the device won't work. It is noticed that some
devices doesn't recover properly, so let's add a dump_stack() as a debug
option, to allow us to track when this happens.

efc52a9484 V4L/DVB (9912): em28xx: fix/improve em28xx locking schema
Changes/fixes on em28xx dev->lock:

- em28xx_init_dev() were unlocking without a previous lock;

- some read ioctls need to lock after the removal of KBL, since a write
  may be happening at the same time an ioctl is reading;

- keep the device locked during all device initialization;

- lock/unlock while reading/writing registers.

cf8c91c3e7 V4L/DVB (9911): em28xx: vidioc_try_fmt_vid_cap() doesn't need any lock
vidioc_try_fmt_vid_cap() just checks if a given resolution is supported.
It doesn't touch on struct em28xx device descriptor. so, there's no need
to lock.

While there, use unlikely() for those values that aren't likely to
occur.
