ASoC: wm8994: Ensure there are enough BCLKs for four channels

2012-08-09T15:31:52+00:00

commit b8edf3e5522735c8ce78b81845f7a1a2d4a08626 upstream.

Otherwise if someone tries to use all four channels on AIF1 with the
device in master mode we won't be able to clock out all the data.

ALSA: hda - Support dock on Lenovo Thinkpad T530 with ALC269VC

2012-08-09T15:31:52+00:00

commit 707fba3fa76a4c8855552f5d4c1a12430c09bce8 upstream.

Lenovo Thinkpad T530 with ALC269VC codec has a dock port but BIOS
doesn't set up the pins properly.  Enable the pins as well as on
Thinkpad X230 Tablet.

ALSA: hda - Fix mute-LED GPIO initialization for IDT codecs

2012-08-09T15:31:52+00:00

commit 1f43f6c1bc8d740e75b4177eb29110858bb5fea2 upstream.

The IDT codecs initializes the GPIO setup for mute LEDs via
snd_hda_sync_vmaster_hook().  This works in most cases except for the
very first call, which is called before PCM and control creations.
Thus before Master switch is set manually via alsactl, the mute LED
may show the wrong state, depending on the polarity.

Now it's fixed by calling the LED-status update function manually when
no vmaster is set yet.

ALSA: hda - Fix polarity of mute LED on HP Mini 210

2012-08-09T15:31:52+00:00

commit ff8a1e274cbc11da6b57849f925b895a212b56c9 upstream.

The commit a3e199732b made the LED working again on HP Mini 210 but
with a wrong polarity.  This patch fixes the polarity for this
machine, and also introduce a new model string "hp-inv-led".

ALSA: hda - Fix mute-LED GPIO setup for HP Mini 210

2012-08-09T15:31:52+00:00

commit a3e199732b8e2b272e82cc1ccc49c35239ed6c5a upstream.

BIOS on HP Mini 210 doesn't provide the proper "HP_Mute_LED" DMI
string, thus the driver doesn't initialize the GPIO, too.  In the
earlier kernel, the driver falls back to GPIO1, but since 3.3 we've
stopped this due to other wrongly advertised machines.

For fixing this particular case, add a new model type to specify the
default polarity explicitly so that the fallback to GPIO1 is handled.

ALSA: hda - Fix invalid D3 of headphone DAC on VT202x codecs

2012-08-09T15:31:52+00:00

commit 6162552b0de6ba80937c3dd53e084967851cd199 upstream.

We've got a bug report about the silent output from the headphone on a
mobo with VT2021, and spotted out that this was because of the wrong
D3 state on the DAC for the headphone output.  The bug is triggered by
the incomplete check for this DAC in set_widgets_power_state_vt1718S().
It checks only the connectivity of the primary output (0x27) but
doesn't consider the path from the headphone pin (0x28).

Now this patch fixes the problem by checking both pins for DAC 0x0b.

ALSA: mpu401: Fix missing initialization of irq field

2012-08-09T15:31:52+00:00

commit bc733d495267a23ef8660220d696c6e549ce30b3 upstream.

The irq field of struct snd_mpu401 is supposed to be initialized to -1.
Since it's set to zero as of now, a probing error before the irq
installation results in a kernel warning "Trying to free already-free
IRQ 0".

ALSA: snd-usb: fix clock source validity index

2012-08-09T15:31:51+00:00

commit aff252a848ce21b431ba822de3dab9c4c94571cb upstream.

uac_clock_source_is_valid() uses the control selector value to access
the bmControls bitmap of the clock source unit. This is wrong, as
control selector values start from 1, while the bitmap uses all
available bits.

In other words, "Clock Validity Control" is stored in D3..2, not D5..4
of the clock selector unit's bmControls.

ALSA: hda - add dock support for Thinkpad X230 Tablet

2012-08-09T15:31:29+00:00

commit 108cc108a3bb42fe4705df1317ff98e1e29428a6 upstream.

Also add a model/fixup string "lenovo-dock", so that other Thinkpad
users will be able to test this fixup easily, to see if it enables
dock I/O for them as well.
