In commit 411674fd18 the tda9875 support was
added to tvaudio. This means that tda9875 is no longer used since mid-2009.
If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.
The original commit message read as follows:
This change allows bttv to use tvaudio for this device. Since this device
has the same i2c address as the tda9874 we need to support both in the same
tvaudio driver. This makes it possible for tvaudio to detect which chip is
used. Originally the tda9875 was only available in the dedicated tda9875
driver, but that makes life very hard for bttv since loading tvaudio might
misdetect a tda9875 as a tda9874.
So there were good reasons for moving the tda9875 code into tvaudio.

The i915 driver normally assumes the video bios has configured several
of the LVDS panel registers, and it just inherits the values. If the
vbios has not run, several of these will need to be setup.
If these are not correct then although the panel looks ok, output from an
HDMI encoder (eg, Chrontel CH7036) will be incorrect.

Many modern devices have features such as DC servos which take time to start.
Currently these are handled by per-widget events but this makes it difficult
to paralleise operations on multiple widgets, meaning delays can end up
being needlessly serialised. By providing a callback to drivers when all
widgets of a given type have been handled during a DAPM sequence the core
allows drivers to start operations separately and wait for them to complete
much more simply.

With larger devices there may be many widgets of the same type in series
in an audio path. Allow drivers to specify an additional level of ordering
within each widget type by adding a subsequence number to widgets and then
splitting operations on widgets so that widgets of the same type but
different sequence numbers are processed separately. A typical example
would be a supply widget which requires that another widget be enabled
to provide power or clocking.
SND_SOC_DAPM_PGA_S() and SND_SOC_DAPM_SUPPLY_S() macros are provided
allowing this to be used with PGAs and supplies as these are the most
commonly affected widgets.

I changed 945's self refresh to work without the need for the driver to
enable/disable self refresh manually based on the idle state of the gpu.
This is much better than enabling/disabling self refresh for various
reasons, including staying in a lower power state for more time and
avoiding the need for cpu cycles.
This was originally done manually to workaround issues with the hardware
hanging. However, since 944001201: drm/i915: enable low power render
writes on GEN3 hardware, automatic CxSR seems stable.

945 class hardware has an interesting quirk in which the vblank
interrupt is not raised if the CPU is in a low power state. (We also
suspect that the memory bus is clocked to the CPU/c-state and not the
GPU so there are secondary starvation issues.) In order to prevent the
most obvious issue of the low of the vblank interrupt (stuttering
compositing that only updates when the mouse is moving) is to install a
PM QoS request to prevent low c-states whilst the GPU is active.

In the olden days it was possible to register a map of ports per device,
but this has long since been abandoned due to the desire to match up with
clkdev and other functionality. As a result, all of the in-tree users
have for some time already been migrated off of such behaviour, while
we've left support code in place to deal with either case. Dropping the
code permits for quite a bit of simplification, so we do that now before
any users of the old interface are able to be added back in.
