2015-04-13ALSA: hda - Expose codec type sysfsTakashi Iwai1-0/+2
The type field of HD-audio codec object should be exposed to user-space so that it can identify which driver type to bind (legacy / asoc). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-13ALSA: ctl: fix to handle several elements added by one operation for ↵Takashi Sakamoto1-5/+11
userspace element An element instance can have several elements with the same feature. Some userspace applications can add such an element instance by add operation with the number of elements. Then, the element instance gets a memory object to keep states of these elements. But the element instance has just one memory object for the elements. This causes the same result to each read/write operations to the different elements. This commit fixes this bug by allocating enough memory objects to the element instance for each of elements.

2015-04-09ALSA: hda/realtek - Fix the regression by widget power-savingTakashi Iwai1-2/+3
While enabling the widget power-saving for ALC269 & co, the important setup was forgotten -- stream_pm ops. Without this setup, the paths for PCM won't be powered up at all. Also, the power_filter callbacks used in ALC269 & co need to chain to the default snd_hda_gen_path_power_filter().

2015-04-09ALSA: hda/generic - Don't override power_filter when power_save_node is setTakashi Iwai1-1/+2
Currently the generic parser sets codec->power_filter when power_save_node flag is set. But this overrides the existing filter that has been already set by the codec driver, thus it looses some features. Instead, set the default power_filter only when it's not set yet.

2015-04-09ALSA: hda/generic - Make snd_hda_gen_path_power_filter() always applicableTakashi Iwai1-0/+4

2015-04-09ALSA: hda/generic - Fix wrong initial power state for fixed pinsTakashi Iwai1-3/+11
When the widget power-saving is enabled, the first automute hook invocation checks through the whole pins and it also tries to synchronize the power state. However, this results in a wrong state because it calls unconditionally snd_hda_jack_detect_state(). This patch adds a check of jack detectability before the actual jack detection call.

2015-04-09ALSA: hda/generic - Check power state cap at updating the widget powerTakashi Iwai1-0/+2

2015-04-09ALSA: hda - Always allow access for POWER_STATE verbs via regmapTakashi Iwai1-5/+5
The hdac regmap code checks whether the codec is powered on while accessing, but there must be an exception -- the verbs to control the power state.

2015-04-08ALSA: hda - Fix headphone pin config for Lifebook T731Takashi Iwai1-0/+9
Some BIOS version of Fujitsu Lifebook T731 seems to set up the headphone pin (0x21) without the assoc number 0x0f while it's set only to the output on the docking port (0x1a). With the recent commit [03ad6a8c93b6: ALSA: hda - Fix "PCM" name being used on one DAC when there are two DACs], this resulted in the weird mixer element mapping where the headphone on the laptop is assigned as a shared volume with the speaker and the docking port is assigned as an individual headphone. This patch improves the situation by correcting the headphone pin config to the more appropriate value.

2015-04-08ALSA: hda - Work around races of power up/down with runtime PMTakashi Iwai7-25/+53
Currently, snd_hdac_power_up()/down() helpers checks whether the codec is being in pm (suspend/resume), and skips the call of runtime get/put during it. This is needed as there are lots of power up/down sequences called in the paths that are also used in the PM itself. An example is found in hda_codec.c::codec_exec_verb(), where this can power up the codec while it may be called again in its power up sequence, too. The above works in most cases, but sometimes we really want to wait for the real power up. For example, the control element get/put may want explicit power up so that the value change is assured to reach to the hardware. Using the current snd_hdac_power_up(), however, results in a race, e.g. when it's called during the runtime suspend is being performed. In the worst case, as found in patch_ca0132.c, it can even lead to the deadlock because the code assumes the power up while it was skipped due to the check above. For dealing with such cases, this patch makes snd_hdac_power_up() and _down() to two variants: with and without in_pm flag check. The version with pm flag check is named as snd_hdac_power_up_pm() while the version without pm flag check is still kept as snd_hdac_power_up(). (Just because the usage of the former is fewer.) Then finally, the patch replaces each call potentially done in PM with the new _pm() variant. In theory, we can implement a unified version -- if we can distinguish the current context whether it's in the pm path. But such an implementation is cumbersome, so leave the code like this a bit messy way for now...
