2012-09-19ALSA: hda - don't create dysfunctional mixer controls for ca0132David Henningsson
commit c41999a23929f30808bae6009d8065052d4d73fd upstream. It's possible that these amps are settable somehow, e g through secret codec verbs, but for now, don't create the controls (as they won't be working anyway, and cause errors in amixer).

2012-09-19ASoC: wm9712: Fix microphone source selectionMark Brown
commit ccf795847a38235ee4a56a24129ce75147d6ba8f upstream. Currently the microphone input source is not selectable as while there is a DAPM widget it's not connected to anything so it won't be properly instantiated. Add something more correct for the input structure to get things going, even though it's not hooked into the rest of the routing map and so won't actually achieve anything except allowing the relevant register bits to be written.

2012-08-09ALSA: hda - Fix mute-LED GPIO initialization for IDT codecsTakashi Iwai
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.

2012-08-09ALSA: hda - Fix mute-LED GPIO setup for HP Mini 210Takashi Iwai
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.

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.

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.

commit c9fe573a6584034670c1a55ee8162d623519cbbf upstream. In sound/soc/codecs/tlv320aic3x.c data = snd_soc_read(codec, AIC3X_PLL_PROGA_REG); snd_soc_write(codec, AIC3X_PLL_PROGA_REG, data | (pll_p << PLLP_SHIFT)); In the above code, pll-p value is OR'ed with previous value without clearing it. Bug is not seen if pll-p value doesn't change across Sampling frequency. However on some platforms (like AM335x EVM-SK), pll-p may have different values across different sampling frequencies. In such case, above code configures the pll with a wrong value. Because of this bug, when a audio stream is played with pll value different from previous stream, audio is heard as differently(like its stretched).

2012-07-16ALSA: hda - Fix power-map regression for HP dv6 & coTakashi Iwai
commit 6e1c39c6b00d9141a82c231ba7c5e5b1716974b2 upstream. The recent fix for power-map controls (commit b0791dda813) caused regressions on some other HP laptops. They have fixed pins but these pins are exposed as jack-detectable. Thus the driver tries to control the power-map dynamically per jack detection where it never gets on. This patch corrects the condition check for fixed pins so that the power-map is set always for these pins. NOTE: this is no simple backport from 3.5 kernel. Since 3.5 kernel had significant code change in the relevant part, I fixed this differently.

It also supports up to 8 audio channels. The sink may not necessarily support all these sample rates and channels. However, as this CPU DAI describes the HDMI source, it makes sense to include them.

2012-06-22ASoC: OMAP: HDMI: Improve how the display state is verifiedRicardo Neri
Before starting to play audio, we need to make sure that the display is active and the current video mode supports audio. instead of using the overlay manager in the machine driver, we use the DSS audio interface's audio_supported function. As we already have a pointer to the correct dssdev, we do not have to look for it every time audio is to be played. Also, the CPU DAI startup function is called earlier than the card hw_param function. Hence and we can detect the state of the display earlier. While there, add a error message if the constraint cannot be applied.

2012-06-22ASoC: OMAP: HDMI: Use the DSS audio interfaceRicardo Neri
Instead of accessing the HDMI IP directly, the CPU DAI driver takes advantage of the audio interface provided by the DSS device driver. The ASoC driver will link the DSS audio functionality with ALSA by calling the appropriate DSS device driver functions at the relevant moments. For this, three new DAI operations are added: trigger, prepare and shutdown operations. At the moment, it is assumed that only one HDMI display is available in the system, as it is the case in OMAP4. However, in the future, one DAI for each HDMI display should be provided.
