e8a7f136f5 [ALSA] hda-intel - Improve HD-audio codec probing robustness
When modem is disabled in the BIOS, detection of the number of codecs
always fails after booting if STATESTS is not cleared first.
This patch fixes this problem and also adds an error check in a place
where a read error would lead to a very large number of pointless loops.

bfc4e86166 [ALSA] Fix CS4270 volume control and optimize I2C operations
The volume control for the CS4270 ASoC driver was inverted - raising the
volume level with alsamixer would decrease the actual volume.
This patch also improves the performance of the I2C code (used to change
register settings) by only performing an I2C write if the new value is

90cf9b8532 [ALSA] ad1838/cs4231 - fix MCE timeout upon initial load
When the ad1848/cs2431 is first being initialized, auto-calibration may not
be set causing a timeout waiting for it in snd_ad1848/cs4231_mce_down().
This has no dire consequences other than an alarming printk, but since what
we need to wait for is for the calibration to _finish_, let's just check for
that instead.
The early chips need a slight delay (as commented -- 5 sample periods) to be
sure that _if_ calibration is going to happen, it has started when we check
While the CS4231A datasheet implies it'll happen immediately on downing MCE,
some testing is showing that there's a window there as well, so just do the
delay everywhere.
Thanks to Krysztof Helt for pinpointing this problem.

dcfb414032 [ALSA] snd-bt87x: Improve support for different board types
Different cards have different audio configurations, but the driver didn't
support this.  The only setting it had was the digital rate.
This patch adds a board configuration list.  Currently, configurable items are
the digital rate and the digital data format (for cards with an external ADC),
a flag for the absence of an external ADC, and a flag for no connection to the
Bt87x internal ADC.
This allows cards that don't use the internal ADC to omit the ALSA 'Bt87x
analog' device and related controls.  Cards without an external ADC can omit
the 'Bt87x digital' device.
In order to support the CS5331A ADC used on the Osprey 440 and 2x0 cards, the
digital format needs to be different than the default.
Support could be added for defining:
  The connections or lack of them to the Bt87x's internal ADC mux
  Multiple sample rates for an external ADC (e.g. Osprey)
  Control of an external mux for an external ADC (e.g. Osprey)
The card definitions for cards other than the Ospreys are kept equivalent to
their old values.  This is likely inaccurate for most cards, as it is doubtful
that both an external and the internal ADC would be used.  Lacking information
on those cards, the behavior is left unchanged.

222fa0b0d2 [ALSA] cs5535audio: fix PRD register save/restore power management race
In the suspend path, we currently save the PRD registers and then disable DMA.
This is racy; the sound hardware might update the PRD register as it finishes
processing some DMA pages between when we've saved the PRD registers and
when DMA actually gets disabled.  Furthermore, we actively check whether or
not DMA is enabled before saving PRD registers; there's no reason to do that,
as the PRD registers should not update when we twiddle the ACC_BM[x]_CMD
register(s).  Worst case, we save the PRD registers twice; even powering
down the ACC shouldn't mess with the PRD registers (according to the 5536
data sheet, section 5.3.7.4, power-down procedure).  This patch reworks
all that to first disable DMA, and then save PRD registers.

bus master DMA, and unsetting it when we tear down the BM's DMA.

Comment in hda_intel.c states that 'the explicit resume is needed only
when POWER_SAVE isn't set', but this is not true.
There is no code that will automaticly power up the codec on resume,
but only code that powers it up when user accesses it. So if user
leaves a sound playing, codec will not be powered
To fix that I check if there are any codecs that should be powered
codec->power_count, and if so I power them up together with main
