Trent Piepho [Fri, 27 Apr 2007 15:31:30 +0000 (12:31 -0300)]
V4L/DVB (5363): Dvb: Remove lgh06xf driver

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.

V4L/DVB (5362): Dvb-pll: add code for doing tuner initialization

Some tuners need or benefit from initialization, to change certain
settings from their power on default values.

Typically, tuners with TUA603x PLLs can benefit from setting the AGC TOP
value to something else.  This patch includes code to set the AGC TOP to
103 dBuV for the Thomson DTT-761x tuners, which I have experimentally
verified gives the best SNR readings, increasing SNR by about 0.19 dB
over the default value.

Other tuners can make use of this as well.  For example, the separate LG
TDVS-H06xF driver's only difference from dvb-pll is this same setting of
AGC TOP value.

V4L/DVB (5361): Dvb-pll: Fix Kconfig files and allow dvb-pll to be optional

A number of drivers selected DVB_PLL when they did not need it, and some
that did need it did not select it.

The DVB_PLL option is given a name and help text, so that it will show up
in the config menu.  DVB_PLL support can be turned on if an out-of-tree
driver needs it.

The standard dvb fe customization support is added to dvb-pll.h.  Since
all modules which select DVB_PLL do so unconditionally, it is not
possible to turn dvb-pll off when an enabled module selects it, unlike
most of the other frontend/tuner drivers.  This is because the users of
dvb-pll have static references to dvb-pll symbols other than the attach
function.  If these references are removed, then dvb-pll will be
disablable as the other frontend/tuner drivers are.

[S390] Improved kernel stack overflow checking.

Recent cvs versions of gcc have support for an improved stack overflow
checking that calculates the size of the guard size for each function.
If the compiler accepts -mstack-size without -mstack-guard then the
new stack check is available. We always want to use the new stack
checker.

[S390] Get rid of console setup functions.

We get this:

Section mismatch: reference to .init.text:con3270_consetup from .data
  between 'con3270' (at offset 0x45c8) and 'con3270_fn'

function and one that returns only 0 remove them.
