* ASoC: tas2552: Correct Boost Auto-Pass Through Control register usagePeter Ujfalusi2015-06-082-14/+13
| | | | | | | | | Correct the bit definition so the code will change the bits what it supposed to change. Also rename the register define to TAS2552_BOOST_APT_CTRL. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: tas2552: Correct the PLL configurationPeter Ujfalusi2015-06-082-54/+95
| | | | | | | | | | | | | | Do not restrict the sampling rate to 44.1/48KHz. The pll_clk clock should be (sampling rate * 512) in all cases. Correct the J.D calculation (the D part was incorrectly calculated). Restore PLL enable status after we are done with the configuration. Implement hardware constraint handling towards the pll_clkin: if D != 0 (in J.D) then 1.1MHz <= pll_clkin <= 9.2MHz needs to be checked. If the PLL setup does not met with this constraint, fall back to BCLK as reference clock, if BCLK fails, use the internal 1.8MHz clock.

* ASoC: tas2552: Configure the WCLK frequency based on the streamPeter Ujfalusi2015-06-052-21/+59
| | | | | | | | | | | Instead of hard wiring the WCLK frequency at probe time do it runtime. The hard wired 88_96KHz was not even setting the correct bits since it was defined as (1 << 6) which will change the I2S_OUT_SEL bit and will leave the amplifier configured for 8KHz. At the same time clean up and fix the CFG3 register bits. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: tas2552: Implement startup/stop sequence as per TRMPeter Ujfalusi2015-06-051-16/+28
| | | | | | | | | | | | | Certain sequence need to be followed in order to have smooth power up and power down performance. Execute this sequence via DAPM_POST widget. Remove patching the RESERVED_0D register at probe time since it has to be handled every time when we stop or start the amplifier. In order to be able to execute the sequence at the correct time, the driver need to request to ignore the pmdown time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ALC256 does not have a mixer nid at 0x0b, and there's no loopback path (the output pins are directly connected to the DACs). This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)" error (and as a result, problems with amixer/alsamixer). If there's pcbeep functionality, it certainly isn't controlled by setting an amp on 0x0b, so disable beep functionality (at least for now).

| * ALSA: usb-audio: Fix audio output on Roland SC-D70 sound moduleTakamichi Horikawa2015-04-212-29/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Roland SC-D70 reports its device class as vendor specific class and the quirk QUIRK_AUDIO_FIXED_ENDPOINT was used for audio output. In the quirks table the sampling rate was hard-coded to 44100 Hz and therefore not worked when the sound module was in 48000 Hz mode. In this change the quirk is changed to QUIRK_AUDIO_STANDARD_INTERFACE but as the sound module reports incorrect bSubframeSize in its descriptors, additional change is made in format.c to detect it and to override it (which uses the existing code for Edirol SD-90). Tested both when the sound module was in 44100 Hz mode and 48000 Hz mode and both audio input and output. MIDI related part of the driver is not touched.

| * ALSA: hda - add AZX_DCAPS_I915_POWERWELL to BaytrailMengdong Lin2015-04-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail). Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared power well with GPU. This power well must be turned on before we reset link to probe the codec, to avoid communication failure with the codec. The side effect is that this power is always ON in S0 because the BYT HDMI codec does not support EPSS or D3ClkStop and so the controller doesn't enter D3 at runtime, and the HDMI codec and analog codec share a single physical HD-A link and so we cannot reset the HD-A link freely when we re-enable the power to use the HDMI codec. Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is okay to bring the HDMI codec back to a functional state after restoring the power. If okay, we can bind the power on/off with the HDMI codec PM without interrupting the analog audio. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * ALSA: hda - only sync BCLK to the display clock for Haswell & BroadwellMengdong Lin2015-04-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Only Intel Haswell and Broadwell have a separate HD-A controller (PCI device 3) for display audio, which needs to get 24MHz HD-A link BCLK from the variable display core clock through vendor specific registers EM4 & EM5. Other platforms (Baytrail, Braswell and Skylake) don't have this feature. So this patch checks the PCI device ID of the controller in haswell_set_bclk() and only sync BCLK for HSW and BDW.

In this case the control flow is: sound_ioctl() -> case SND_DEV_SEQ: case SND_DEV_SEQ2: sequencer_ioctl() -> case SNDCTL_SEQ_OUTOFBAND: spin_lock_irqsave(&lock,flags); play_event(); -> case EV_TIMING: seq_timing_event() -> case TMR_ECHO: seq_copy_to_input() -> spin_lock_irqsave(&lock,flags); It seems that spin_lock_irqsave() around play_event() is not necessary, because the only other call location in seq_startplay() makes the call without acquiring spinlock. So, the patch just removes spinlocks around play_event(). By the way, it removes unreachable code in seq_timing_event(), since (seq_mode == SEQ_2) case is handled in the beginning.

It must be protected by locking mechanism to avoid the list changing while extcon_update_state() is executed. 3. Fix minor issue of extcon drviers - Fix cable name by using the capital letter instead of small letter on extcon-max77693.c driver. - Clean-up code of extcon-arizona.c to detect headphone cable. - Fix the wrong return type and variable type on extcon-max77843.c. - Fix the checkpatch warning of all extcon drivers.

This patch renames the function to arizona_extcon_hp_clamp, as it controls clamping on the headphone output.

These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

Also, HD-audio receives the regmap support replacing the in-house cache register cache code. These changes shouldn't impact the existing behavior, but rather refactoring. In addition, HD-audio got the code split to a core library part and the "legacy" driver parts. This is a preliminary work for adapting the upcoming ASoC HD-audio driver, and the whole transition is still work in progress, likely finished in 4.1. Along with them, there are many updates in ASoC area as usual, too: lots of cleanups, Intel code shuffling, etc. Here are some highlights: ALSA core: - PCM: the audio timestamp / wallclock enhancement - PCM: fixes in DPCM management - Fixes / cleanups of user-space control element management - Sequencer: modernization using the standard bus HD-audio: - Modernization using the standard bus - Regmap support - Use standard runtime PM for codec power saving - Widget-path based power-saving for IDT, VIA and Realtek codecs - Reorganized sysfs entries for each codec object - More Dell headset support ASoC: - Move of jack registration to the card level - Lots of ASoC cleanups, mainly moving things from the CODEC level to the card level - Support for DAPM routes specified by both the machine driver and DT - Continuing improvements to rcar - pcm512x enhacements - Intel platforms updates - rt5670 updates / fixes - New platforms / devices: some non-DSP Qualcomm platforms, Google's Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC Misc: - ice1724: Improved ESI W192M support - emu10k1: Emu 1010 fixes/enhancement" * tag 'sound-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) ALSA: hda - set GET bit when adding a vendor verb to the codec regmap ALSA: hda/realtek - Enable the ALC292 dock fixup on the Thinkpad T450 ALSA: hda - Fix another race in runtime PM refcounting ALSA: hda - Expose codec type sysfs ALSA: ctl: fix to handle several elements added by one operation for userspace element ASoC: Intel: fix array_size.cocci warnings ASoC: n810: Automatically disconnect non-connected pins ASoC: n810: Consistently pass the card DAPM context to n810_ext_control() ASoC: davinci-evm: Use card DAPM context to access widgets ASoC: mop500_ab8500: Use card DAPM context to access widgets ASoC: wm1133-ev1: Use card DAPM context to access widgets ASoC: atmel: Improve machine driver compile test coverage ASoC: atmel: Add dependency to SND_SOC_I2C_AND_SPI where necessary ALSA: control: Fix a typo of SNDRV_CTL_ELEM_ACCESS_TLV_* with SNDRV_CTL_TLV_OP_* ALSA: usb-audio: Don't attempt to get Microsoft Lifecam Cinema sample rate ASoC: rnsd: fix build regression without CONFIG_OF ALSA: emu10k1: add toggles for E-mu 1010 optical ports ALSA: ctl: fill identical information to return value when adding userspace elements ALSA: ctl: fix a bug to return no identical information in info operation for userspace controls ALSA: ctl: confirm to return all identical information in 'activate' event ...

This patch sets the GET bit (bit 11) when adding the verb so that its peer vendor 'get' verb is actually added. This can avoid I/O error when writing the 'set' verb thru remap, since HD-A regmap internally looks up a writable vendor verb with GET bit set at first.
