2017-02-08ASoC: Intel: Skylake: Add route change to nau88l25_max98357a machineJeeja KP
To support MST moved pin to port, this changes the routes based on port. So change the route in nau88l25_max98357a machine. Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-02-08ASoC: hdac_hdmi: Begin to add support for DP Multi-stream audioJeeja KP
With MST each pin contains several ports to which device can be connected. As a preparatory work to support DP MST this patch adds below changes: 1. Defines the port structure and moves all stream related information like ELD, converter list, chmap to port. 2. Creates ports for each pin based on the max_ports support. 3. Based on Pin-Port combination creates DAPM Mux widget instead of Pin to allow user to select a converter. 4. Port zero is the default port when pin does not support MST.

2017-02-08ALSA: seq: Fix race at creating a queueTakashi Iwai
When a sequencer queue is created in snd_seq_queue_alloc(),it adds the new queue element to the public list before referencing it. Thus the queue might be deleted before the call of snd_seq_queue_use(), and it results in the use-after-free error, as spotted by syzkaller. The fix is to reference the queue object at the right time. Reported-by: Dmitry Vyukov <dvyukov@google.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-07ALSA: x86: Cache AUD_CONFIG register valueTakashi Iwai
At enabling the audio, we modify AUD_CONFIG register bit 0. So far, it does read-modify-write procedure with a special hack for the channel bits due to the silicon bug. But we can optimize it by remembering the AUD_CONFIG register value privately. This simplifies the things a lot. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-07ALSA: x86: Rearrange definesTakashi Iwai
We have two header files and everything is mixed up chaotically. Move the chip-specific definitions like the hardware registers to intel_hdmi_lpe_audio.h, and the rest, the implementation specific stuff into intel_hdmi_audio.h. In addition, put some more comments to the register fields, and fix the incorrect name prefix for AUD_HDMI_STATUS bits, too. The whole changes are merely a code shuffling, and there is no functional change. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-07ALSA: x86: mark hdmi suspend/resume functions as __maybe_unusedArnd Bergmann

2017-02-07ALSA: x86: Fix driver name string overflowTakashi Iwai
The driver sets card->driver name string over its size (16 bytes). Shorten the name string to fit with it. Also, set more verbose string to card->shortname and ->longname. This doesn't have to be identical with card->driver at all. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-07ALSA: x86: Rename had_enable_audio_int() to had_ack_irqs()Takashi Iwai
had_enable_audio_int() came from the LPE audio shell set_caps callback with ENABLE_INT and DISABLE_INT caps. I interpreted as these correspond to enabling / disabling the audio interface, but the actual implementation is only to clear (send ACK) to both BUFFER_DONE and BUFFER_UNDERRUN interrupts unconditionally. And, there is no counterpart, DISABLE_INT, code at all. For avoiding the further misunderstanding, rename the function to the more fitting one, had_ack_irqs(), and drop the calls with enable=false in allover places. There is no functional changes at all. After this patch, there is only one caller at the PCM trigger start. Then it's doubtful whether this call is still really needed or not; I bet it not, but let's stay in the safer side for now and keep it as was. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-07ALSA: x86: Drop suspicious U24 format supportTakashi Iwai
U24 format is declared to be supported by the driver, but this looks really doubtful, as there is no corresponding code. Better to drop it. This format is very uncommon, so there should be practically no impact by this change. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-07ALSA: line6: Always setup isochronous transfer propertiesAndrej Krutak

This reverts commit f6a0dd107ad0c8b59d1c9735eea4b8cb9f460949. The commit caused a regression on LINE6 Transport that has no control caps. Although reverting the commit may result back in a spurious error message for some device again, it's the simplest regression fix, hence it's taken as is at first. The further code fix will follow later.

2017-02-06ASoC: fix ES8328_I2C/SPI dependenciesArnd Bergmann
The two front-ends to the codec can now be selected individually, but fail to build when the bus support is missing: sound/built-in.o: In function `es8328_spi_probe': es8328-spi.c:(.text+0x125854): undefined reference to `__devm_regmap_init_spi' sound/built-in.o: In function `es8328_spi_driver_init': es8328-spi.c:(.init.text+0x3589): undefined reference to `__spi_register_driver' Related to this, the added dependency on SND_SOC_ES8328 breaks: warning: (SND_SOC_ALL_CODECS) selects SND_SOC_ES8328_I2C which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_ES8328 && I2C) This adds the respective Kconfig dependencies and changes SND_SOC_ES8328 to a hidden symbol that is selected implicitly by the two more specific options, as we do for some other codecs. We have to remove the 'depends on' for SND_SOC_IMX_ES8328 in the same step to avoid a recursive dependency.

2017-02-06ALSA: seq: Don't handle loop timeout at snd_seq_pool_done()Takashi Iwai
snd_seq_pool_done() syncs with closing of all opened threads, but it aborts the wait loop with a timeout, and proceeds to the release resource even if not all threads have been closed. The timeout was 5 seconds, and if you run a crazy stuff, it can exceed easily, and may result in the access of the invalid memory address -- this is what syzkaller detected in a bug report. As a fix, let the code graduate from naiveness, simply remove the loop timeout.

2017-02-06ALSA: x86: Refactor PCM process engineTakashi Iwai
This is again a big rewrite of the driver; now it touches the code to process PCM stream transfers. The most fundamental change is that the driver may support more than four periods. Instead of keeping the same index between both the ring buffer (with the fixed four buffer descriptors) and the PCM buffer periods, we keep difference indices for both (bd_head and pcm_head fields). In addition, when the periods are more than four, we need to track both head and next indices. That is, we now have three indices: bd_head, pcm_head and pcm_filled. Also, the driver works better for periods < 4, too: the remaining BDs out of four are marked as invalid, so that the hardware skips those BDs in its loop. By this flexibility, we can use even ALSA-lib dmix plugin, which requires 16 periods as default. The buffer size could be up to 20bit, so the max buffer size was increased accordingly. However, the buffer pre-allocation is kept as the old value (600kB) as default. The reason is the limited number of BDs: since it doesn't suffice for the useful SG page management that can fit with the usual page allocator like some other drivers, we have to still allocate continuous pages, hence we shouldn't take too big memories there.

2017-02-05ALSA: x86: Don't check connection in lowlevel accessorsTakashi Iwai
The lowlevel register read/write don't have to be careful about the connection state. It should be checked in the caller side instead. By dropping the check, we can simplify the code, and readability. This patch also refacors the functions slightly: namely, - drop the useless always-zero return values - fold the inline functions to the main accessor functions themselves - move the DP audio hack for AUD_CONFIG to the caller side - simplify snd_intelhad_eanble_audio() and drop the unused had_read_modify() Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-05ALSA: x86: Explicit specify 32bit DMATakashi Iwai

2017-02-04ASoC: rockchip: Add machine driver for RK3288 boards that use analog/HDMIRomain Perier
The driver is used for Rockchip rk3288-based boards using a configurable analog output (can be an headphone) and the built-in HDMI audio output that is part of the RK3288 SoCs and use the Alsa HDMI codec driver. For some rk3288-based boards the analog output and the hdmi audio are plugged on the same i2s line, so we have to do the same in the driver by using a DAI link CPU to multicodecs. This configuration can be found for example on the Radxa Rock2 or the Firefly-RK3288.

2017-02-03ALSA: x86: Rename drv_status to connectedTakashi Iwai
After the rewrite of the runtime PM code, we have only two driver status: CONNECTED and DISCONNECTED. So it's clearer to use a boolean flag, and name it easier one, "connected". Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-03ALSA: x86: Yet more tidy-up and clean-upsTakashi Iwai

Like other drivers, expose the ELD bytes via a control element so that user-space can parse it. For the simplicity, the code to register the ctl elements is refactored using an array.

2017-02-03ALSA: x86: Reduce redundant register field namesTakashi Iwai
Currently each register definition contains the own prefix in the union struct itself; for example, union aud_ch_status_0 has status_0_regx and status_0_regval fields. These are simply superfluous, since usually the type of the variable is seen in its declaration or in its name. In this patch, we cut off these prefixes.

2017-02-03ALSA: x86: Move stream status into pcm_stream_infoTakashi Iwai
The only remaining field in struct had_stream_data is stream_type that holds the current stream status. Such information fits better in struct pcm_stream_info, so move it as a boolean "running" field to be clearer. This allows us to get rid or had_stream_data definition and references. Also, the superfluous status check get removed in a couple of places where we can call PCM helpers in anyway. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-03ALSA: x86: Implement runtime PMTakashi Iwai
Although the driver has some PM callbacks, it doesn't do it right: - the suspend callback doesn't handle to suspend the running PCM, - the runtime PM ops are missing, - pm_runtime_get_sync() isn't used at the right place. This patch covers the above and provides the basic runtime PM functionality. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-03ALSA: x86: Properly manage PCM substream lifetypeTakashi Iwai
The PCM substream is referred not only in the PCM callbacks but also in the irq handler and in the hotplug/unplug codes. The latter code paths don't take the PCM lock, thus the PCM may be released unexpectedly while calling PCM helper functions or accessing pcm->runtime fields. This patch implements a simple refcount to assure the PCM substream accessibility while the other codes are accessing. It needed some code refactoring in the relevant functions for avoiding the doubly spinlocks. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-02-03ALSA: x86: Drop unused fields from pcm_stream_infoTakashi Iwai
