According to i.MX27 Reference Manual (p 1593) TXBIT0 bit selects
whether the most significant or the less significant part of the
data word written to the FIFO is transmitted.
As DSP_A is the same as DSP_B with a data offset of 1 bit, it
doesn't make any sense to remove TXBIT0 bit here.

Recent enhancements in the bias management means that we might not be
in standby when the CODEC is idle and can have active widgets without
being in full power mode but the shutdown functionality assumes these
things. Add checks for the bias level at each stage so that we don't
do transitions other than the ON->PREPARE->STANDBY->OFF ones that the
drivers are expecting.

A couple of small, driver specific fixes - nothing too exciting going
on.
Chip designers frequently include things like the enable and disable
controls for algorithms in the register blocks which also hold the
coefficients. Since it's desirable to split out the enable/disable
control from userspace the plain SND_SOC_BYTES() isn't optimal for
these devices.
Add a SND_SOC_BYTES_MASK() which allows a bitmask from the first word
of the block to be excluded from the control. This supports the needs
of devices I've looked at and lets us have a reasonably simple API.
Further controls can be added in future if that's needed.

Allow devices to export blocks of registers to the application layer,
intended for use for reading and writing coefficient data which can't
usefully be worked with by the kernel at runtime (for example, due to
requiring complex and expensive calculations or being the results of
callibration procedures). Currently drivers are using platform data to
provide configurations for coefficient blocks which isn't at all
convenient for runtime management or configuration development.
Currently only devices using regmap are supported, an error will be
generated for any attempt to work with a byte control on a non-regmap
device. There's no fundamental block to other devices so support could
be added if required.

Merge tag 'topic/introspection' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap into HEAD
New interfaces to allow other subsystems to gather information about the
regmap, allowing them to build further subsystem specific generic
features on top of the regmap.
Merged into ASoC in order to allow us to implement SND_SOC_BYTES_MASK()
controls which need to know the word size of the underlying registers.
When an external capacitor is connected to MICBIAS2 on devices with
jack detection (which is not required but may be done in some systems)
then the loading may mean that better performance is obtained when

this.

A few clean-ups for post-static-quirk time:
- Call alc_auto_init_std() statically in alc_init() instead of setting
spec->init_hook in each caller. spec->init_hook field is left
unused for any future use.
- Move the call of set_capture_mixer() to to alc_parse_auto_config()
instead of each caller.
- Get rid of the ADC-filling and imux check in each parser function.
This is no longer needed since the auto-parser always check ADCs and
imux. It was only for the static quirks.
- Kill unused defines

When the machine has two speakers but wants to put more multi-io
jacks, the parser shouldn't consider about the shared DAC but try to
assign the individual DACs. Otherwise the channel mapping would be
fairly confused and lead to the wrong DACs.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
When the multi-io is added to the two speaker output configuration,
the parser would try to add yet another "Bass Speaker" control since
it checks only cfg->line_outs. Add a workaround for it by simply
passing the channel name in the case of multi-io outputs.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
Even if the outputs are using shared DACs, we can still create individual
mute siwtches since they are assigned per pin. This allows to create,
e.g. Speaker and Bass Speaker mute switches while the single volume is
used for these outputs.

Since alc880_quirks.c is removed, alc882_quirks.c has to be adjusted

to the remaining alc882 quirks, but these shall be killed sooner or
