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

2012-08-09T23:25:11Z

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. Reported-and-tested-by: Mario Signed-off-by: Takashi Iwai Signed-off-by: Ben Hutchings

ALSA: snd-usb: fix clock source validity index

2012-08-09T23:25:11Z

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.

ASoC: wm8962: Allow VMID time to fully ramp

2012-08-09T23:25:08Z

ALSA: mpu401: Fix missing initialization of irq field

2012-08-09T23:24:53Z

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

2012-08-09T23:24:52Z

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.

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

2012-08-09T23:24:48Z

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. Signed-off-by: Mark Brown Signed-off-by: Ben Hutchings

ALSA: hda - add dock support for Thinkpad X230 Tablet

2012-08-09T23:24:36Z

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.

ASoC: dapm: Fix _PRE and _POST events for DAPM performance improvements

2012-08-02T13:37:59Z

commit 0ff97ebf0804d2e519d578fcb4db03f104d2ca8c upstream. Ever since the DAPM performance improvements we've been marking all widgets as not dirty after each DAPM run. Since _PRE and _POST events aren't part of the DAPM graph this has rendered them non-functional, they will never be marked dirty again and thus will never be run again. Fix this by skipping them when marking widgets as not dirty. Signed-off-by: Mark Brown Acked-by: Liam Girdwood Signed-off-by: Ben Hutchings

ALSA: hda - Turn on PIN_OUT from hdmi playback prepare.

2012-08-02T13:37:53Z

commit 9e76e6d031482194a5b24d8e9ab88063fbd6b4b5 upstream. Turn on the pin widget's PIN_OUT bit from playback prepare. The pin is enabled in open, but is disabled in hdmi_init_pin which is called during system resume. This causes a system suspend/resume during playback to mute HDMI/DP. Enabling the pin in prepare instead of open allows calling snd_pcm_prepare after a system resume to restore audio. Signed-off-by: Dylan Reid Signed-off-by: Takashi Iwai Signed-off-by: Ben Hutchings

ALSA: hda - Add support for Realtek ALC282

2012-08-02T13:37:52Z

commit 4e01ec636e64707d202a1ca21a47bbc6d53085b7 upstream. This codec has a separate dmic path (separate dmic only ADC), and thus it looks mostly like ALC275.
