2015-06-11ALSA: hda - Re-add the lost fake mute supportTakashi Iwai
Yet another regression by the transition to regmap cache; for better usability, we had the fake mute control using the zero amp value for Conexant codecs, and this was forgotten in the new hda core code. Since the bits 4-7 are unused for the amp registers (as we follow the syntax of AMP_GET verb), the bit 4 is now used to indicate the fake mute. For setting this flag, snd_hda_codec_amp_update() becomes a function from a simple macro. The bonus is that it gained a proper function description. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-04-13ALSA: hda - Fix another race in runtime PM refcountingTakashi Iwai
Although some races in runtime PM refcount was fixed by the commit [664c715573c2: ALSA: hda - Work around races of power up/down with runtime PM], there is still a race in the following case: CPU0: CPU1 : runtime suspend: codec->in_pm = 1 snd_hdac_power_up_pm(): pm_runtime_get_sync() skipped suspend finished: codec->in_pm = 0 snd_hdac_power_down_pm(): pm_runtime_put_*() is called! For avoiding this situation, increment in_pm flag atomically when it's non-zero, and decrement accordingly, to ensure that in_pm is set consistently for the whole concurrent operations. Also, since atomic_inc_not_zero() and atomic_dec_if_positive() are lengthy inline functions, move snd_hdac_power_up_pm() and _down_pm() to sound/hda/hdac_device.c as no inline functions.

2015-04-08ALSA: hda - Work around races of power up/down with runtime PMTakashi Iwai
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...

2015-04-04ALSA: hda - Sync node attributes at resume from widget power savingTakashi Iwai
So far we assumed that the node attributes like amp values remain during the power state transition of the node itself. While this is true for IDT/STAC codecs I've tested, but some other codecs don't seem behaving in that way. This patch implements a partial sync mechanism specific to the given widget node. Now we've merged the regmap support, and it can be easily written with regcache_sync_region(). Tested-by: Hui Wang <hui.wang@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-03-26ASoC: simple-card: Remove support for setting differing DAI formatsLars-Peter Clausen
Having to set different formats on the CPU side and the CODEC side of a DAI link is usually indication that something is terribly wrong and in most cases is a result of a broken driver that implements a set_fmt() callback which does not follow the specification. In the past this feature has been used to work around broken drivers, rather than fixing them. We don't really want to encourage this, so remove support for setting different formats on both ends of the link. Along the way switch to static DAI format setup by setting the the dai_fmt field of the snd_soc_dai_link rather than calling snd_soc_dai_fmt().

2015-03-23ALSA: hda - Add cache support for COEF read/writeTakashi Iwai
The 16bit COEF read/write is pretty standard for many codecs, and they can be cached in most cases -- more importantly, they need to be restored at resume. For making this easier, add the cache support to regmap. If the codec driver wants to cache the COEF access, set codec->cache_coef flag and issue AC_VERB_GET_PROC_COEF with the coef index in LSB 8 bits. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-03-23ALSA: hda - Add a fake stereo amp register supportTakashi Iwai
HD-audio spec is inconvenient regarding the handling of stereo volume controls. It can set and get only single channel at once (although there is a special option to set the same value to both channels). This patch provides a fake pseudo-register via the regmap access so that the stereo channels can be read and written by a single call. It'd be useful, for example, for implementing DAPM widgets. A stereo amp pseudo register consists of the encoding like the normal amp verbs but it has both SET_LEFT (bit 13) and SET_RIGHT (bit 12) bits set. The regmap reads and writes a 16bit value for this pseudo register where the upper 8bit is for the right chanel and the lower 8bit for the left channel. Note that the driver doesn't recognize conflicts when both stereo and mono channel registers are mixed. Mixing them would certainly confuse the operation. So, use carefully.

2015-03-23ALSA: hda - Allow driver to add vendor-specific verbs for regmapTakashi Iwai

2015-03-23ALSA: hda - Use regmap for parameter caches, tooTakashi Iwai
The amp hash table was used for recording the cached reads of some capability values like pin caps or amp caps. Now all these are moved to regmap as well. One addition to the regmap helper is codec->caps_overwriting flag. This is set in snd_hdac_override_parm(), and the regmap helper accepts any register while this flag is set, so that it can overwrite even the read-only verb like AC_VERB_PARAMETERS. The flag is cleared immediately in snd_hdac_override_parm(), as it's a once-off flag. Along with these changes, the no longer needed amp hash and relevant fields are removed from hda_codec struct now. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-03-23ALSA: hda - Implement uncached version of parameter readsTakashi Iwai

2015-03-23ALSA: hda - Add regmap supportTakashi Iwai
This patch adds an infrastructure to support regmap-based verb accesses. Because o the asymmetric nature of HD-audio verbs, especially the amp verbs, we need to translate the verbs as a sort of pseudo registers to be mapped uniquely in regmap. In this patch, a pseudo register is built from the NID, the AC_VERB_GET_* and 8bit parameters, i.e. almost in the form to be sent to HD-audio bus but without codec address field. OTOH, for writing, the same pseudo register is translated to AC_VERB_SET_* automatically. The AC_VERB_SET_AMP_* verb is re-encoded from the corresponding AC_VERB_GET_AMP_* verb and parameter at writing. Some verbs has a single command for read but multiple for writes. A write for such a verb is split automatically to multiple verbs. The patch provides also a few handy helper functions. They are designed to be accessible even without regmap. When no regmap is set up (e.g. before the codec device instantiation), the direct hardware access is used. Also, it tries to avoid the unnecessary power-up. The power up/down sequence is performed only on demand. The codec driver needs to call snd_hdac_regmap_exit() and snd_hdac_regmap_exit() at probe and remove if it wants the regmap access. There is one flag added to hdac_device. When the flag lazy_cache is set, regmap helper ignores a write for a suspended device and returns as if it was actually written. It reduces the hardware access pretty much, e.g. when adjusting the mixer volume while in idle. This assumes that the driver will sync the cache later at resume properly, so use it carefully.

2015-03-23ALSA: hda - Add widget sysfs treeTakashi Iwai
This patch changes the sysfs files assigned to the codec device on the bus which were formerly identical with hwdep sysfs files. Now it shows only a few core parameter, vendor_id, subsystem_id, revision_id, afg, mfg, vendor_name and chip_name. In addition, now a widget tree is added to the bus device sysfs directory for showing the widget topology and attributes. It's just a flat tree consisting of subdirectories named as the widget NID including various attributes like widget capability bits. The AFG (usually NID 0x01) is always found there, and it contains always amp_in_caps, amp_out_caps and power_caps files. Each of these attributes show a single value. The rest are the widget nodes belonging to that AFG. Note that the child node might not start from 0x02 but from another value like 0x0a. Each child node may contain caps, pin_caps, amp_in_caps, amp_out_caps, power_caps and connections files. The caps (representing the widget capability bits) always contain a value. The rest may contain value(s) if the attribute exists on the node. Only connections file show multiple values while other attributes have zero or one single value. An example of ls -R output is like below: % ls -R /sys/bus/hdaudio/devices/hdaudioC0D0/ /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/: 01/ 04/ 07/ 0a/ 0d/ 10/ 13/ 16/ 19/ 1c/ 1f/ 22/ 02/ 05/ 08/ 0b/ 0e/ 11/ 14/ 17/ 1a/ 1d/ 20/ 23/ 03/ 06/ 09/ 0c/ 0f/ 12/ 15/ 18/ 1b/ 1e/ 21/ /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/01: amp_in_caps amp_out_caps power_caps /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/02: amp_in_caps amp_out_caps caps connections pin_caps pin_cfg power_caps /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/03: .....

2015-03-04ASoC: Allow to register jacks at the card levelLars-Peter Clausen
Jacks are typically card level elements, but are currently registered with a CODEC. When it was originally introduced snd_soc_jack_new() took a snd_soc_card as its parameter, but at that time DAPM was only implemented at the CODEC level and there was only one CODEC per card. This made it clear which CODEC to use for the jack DAPM operations. But the multi-component patchset added support for having multiple CODECs per card and with it the API was updated to register jacks with a specific CODEC instance instead. Subsequently DAPM support at the card level has been introduced, but the snd_soc_jack_new() API has so remained unchanged. This leaves us with the issue that the DAPM pins that are managed by the jack detection logic usually are part of the card DAPM context but are accessed through a CODEC DAPM context. Currently this works fine, but might break in the future if we take a more hierarchical approach to DAPM contexts. Furthermore with componentization progressing systems that do not register a snd_soc_codec might appear, while these system may still want to able to register a jack. This patch addresses these issues by adding a new function called snd_soc_card_jack_new() that can be used to register jacks with the card rather than a CODEC. This new function is mostly identical to snd_soc_jack_new() except that it additionally allows to directly specify the DAPM pins associated with the jack. This was done since most users of snd_soc_jack_new() typically call snd_soc_jack_add_pins() right after it, which is not necessary with the new API and allows to reduce the amount of boiler plate code. The old snd_soc_jack_new() is re-implemented as a wrapper around snd_soc_card_jack_new(). Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
