The ioremap one was reported in October 2007 (Bug 9146), the kmalloc one
was blindingly obvious while looking at the ioremap one

The bug suggests some other configuration for lots of I/O memory (32MB per
device is ioremapped) but I'll leave that to the real maintainers

Shared memory mappings on nommu machines require a get_unmapped_area
file operation that suggests an address for the mapping. This patch
adds a way for v4l2 drivers to provide this callback.

Separate tuning table for DVB-C solves tuning problem at 388MHz

TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.

This is suggested by the name of the table: tda827xa_dvbt.

Added a table for DVB-C with the name tda827xa_dvbc.

Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.

This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c

The tda827x.c gives the following warning message when debug=1:

tda827x: tda827x_config not defined, cannot set LNA gain!

Solved this by adding a tda827x_config struct in budget-ci.c.

Remove ancient IVTV_IOC_G_CODEC and IVTV_IOC_S_CODEC ioctl functions
from the pvrusb2 driver.  These are very very old, were non-standard,
and were only present to keep MythTV happy (their implementation did
nothing except to report success).  That was long ago; no recent
versions of MythTV should require this anymore.

This change removes the old i2c module controlling layer from the
pvrusb2 driver.  This is code that first had appeared in the driver
back in December 2005.  It's history.  Now we use v4l2-subdev.  Please
note also that with this change, the driver will no longer be usable
in kernels older that 2.6.22.

The v4l2-subdev infrastructure requires that an initialization call
must be issued to all attached sub-devices before normal operation can
start.  This change satisfies that requirement.

When a pvrusb2 driver instance first initializes, we need to be sure
to send out a complete state update for everything to all attached
modules.  The old i2c layer did this by keeping a separate mask of
"stale" bits for each attached module - and setting that mask to all
stale when that module attaches.  But the new sub-device adaptation
I've implemented here no longer has per-module stale bits.  So instead
there's now a global "force dirty" bit that is set upon instance
initialization, before the sub-devices are attached.  After the first
update, this bit is cleared, allowing for normal update-on-dirty
behavior.  In this manner, we ensure that all sub-devices have been
properly synchronized at initialization.
