PX-BCUD has the following components:
USB interface: Empia EM28178
Demodulator: Toshiba TC90532 (works by code for TC90522)
Tuner: Next version of Sharp QM1D1C0042
em28xx_dvb_init(): add init code for PLEX PX-BCUD with calling
px_bcud_init() that does things like pin configuration.
qm1d1c0042_init(): support the next version of QM1D1C0042, change to
choose an appropriate array of initial registers by reading chip id.

Detect if firmware is running run-time and download / start it only
when needed. Detection is done by reading IF frequency value.
Garbage value is returned by firmware when it is not running,
otherwise correct value is returned.

This issue was detected by using the Coccinelle software.
1. Let us return directly if a call of the regmap_write() function failed.
2. Delete the jump label "err" then.

A previous patch added a check if the firmware is too big, but it didn't
set the return error code with the right value.
[mchehab@osg.samsung.com: I ended by applying a v1 of Laura's patch, without
the proper return code. This patch contains the difference between v2 and v1 of
the Laura's "si2157: Bounds check firmware" patch]

The get_state()/set_state and the corresponding data types
(struct tuner_state and enum tuner_param) are old DVB interfaces
that came from the DVBv3 time.
Nowadays, set_params() provide a better way to set the tuner
and demod parameters. So, no need to keep those legacy stuff,
as all drivers that were using it got converted.
With this patch, all kABI elements at dvb_frontend.h are now
documented.

When reading the firmware and sending commands, the length
must be bounds checked to avoid overrunning the size of the command
buffer and smashing the stack if the firmware is not in the
expected format. Add the proper check.

Make the TV tuners menu visible when compile-testing, to allow
selecting additional drivers on top of the drivers that are already
automatically selected if MEDIA_SUBDRV_AUTOSELECT is enabled.
Without this, many drivers stay disabled during e.g. allmodconfig.

On alpha, gcc warns a log about signed/unsigned ballance, with
produces 3185 warnings. Ok, this is bogus, but it indicates that
the declaration at V4L2 side is not consistent with the one at
I2C.
With this trivial patch, the number of errors reduce to 2959
warnings. Still too much, but it is 7.1% less. So let's do it.

* Rename device state from 's' to 'dev'.
* Move single include to driver private header.
* Change error handling type of each function to one I tend use
nowadays.
* Remove dummy register write from init. Even Windows driver does this
multiple times remove it as I have never seen any I2C errors.
* Define I2C client pointer for each function and use it.
* Do not clean tuner ops during driver remove - not needed.
* Disable sysfs device bind / unbind. We are not allowed manually
bind / unbind device from the driver currently.
* Rename some other variables.

The chips supported by the si2157 driver have two IF outputs (either
pins 12+13 or pins 9+11). Instead of hardcoding the output to be used
add an option to choose which output shall be used.
As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
keep bisectability.

That solves several merge conflicts:
Documentation/DocBook/media/v4l/subdev-formats.xml
Documentation/devicetree/bindings/vendor-prefixes.txt
drivers/staging/media/mn88473/mn88473.c
include/linux/kconfig.h
include/uapi/linux/media-bus-format.h
The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.
