This patch enables runtime power management(runtime PM) support for hda. pm_runtime_enable() and pm_runtime_disable() are added during device probe and remove respectively. The runtime PM callbacks will be forbidden if hda controller does not have support for runtime PM. pm_runtime_get_sync() and pm_runtime_put() are added for hda register access. The callbacks for above will be added in subsequent patches. Signed-off-by:

Fireface UFX was shipped by RME GmbH in 2012. This model supports later protocol for management of isochronous communication and synchronization of sampling transmission frequency. This commit adds support for the model. At present, it's not clear how to encode MIDI messages and decide destination address for asynchronous transaction, thus this commit adds support for isochronous communication for PCM frames only.

In a series of Fireface, latter protocol has no way for drivers to retrieve current clock configuration. On the other hand, this driver has proc node for it. This commit removes a proc node to dump both clock configuration and synchronization status in one proc node. Signed-off-by:

Pull the PCM suspend improvement / cleanup. This moves the most of snd_pcm_suspend*() calls into PCM's own device PM ops. There should be no change from the functionality POV. Signed-off-by:

ATIIXP driver supports the full PCM resume and saves/restores the running PCM pointer. This used to be done in the suspend and resume callbacks together with snd_pcm_suspend() call. But since we moved the snd_pcm_supsend*() call in PCM device PM ops, this should be moved to a more appropriate place, i.e. the trigger callback. Along with the movement of the PCM suspend/resume code, remove the superfluous snd_pcm_suspend_all() call, too. Reviewed-by:

Until now we rely on each driver calling snd_pcm_suspend*() explicitly at its own PM handling. However, this can be done far more easily by setting the PM ops to each actual snd_pcm device object. This patch adds the device_type object for PCM stream and assigns to each PCM stream object. The type contains only the PM ops for system suspend; we don't need to deal with the resume in general. The suspend hook simply calls snd_pcm_suspend_all() for the given PCM streams. This implies that the PM order is correctly put, i.e. PCM is suspended before the main (or codec) driver, which should be true in general. If a special ordering is needed, you'd need to adjust the device PM order manually later. This patch introduces a new flag, snd_pcm.no_device_suspend, too. With this flag set, the PCM device object won't invoke snd_pcm_suspend_all() by itself. This is needed for ASoC who wants to manage the PM call orders in its serialized way, and the flag is set in soc_new_pcm() as default. For the non-ASoC world, we can get rid of the manual snd_pcm_suspend calls. This will be done in the later patches. Reviewed-by:

Program codec stripe through AC_VERB_SET_STRIPE_CONTROL to use multiple sdo lines if supported. Audio needs to be striped across number of sdo lines for simultaneous playbacks of higher resolutions to work. This needs to be implemented only for an Audio Output Converter and only if the stripe bit(AC_WCAP_STRIPE) of Audio Widget Capabilities parameter is 1. Signed-off-by:

Platforms having multiple SORs and hdmi/dp sinks require higher bandwidth to support simultaneous playbacks of higher resolution. If hda controller supports multiple SDO lines, STRIPE can be used to indicate how many of the SDO lines the stream should be striped across. During stream start stripe control bits are programmed to use given number of sdo lines and the same is cleared during stream stop. Signed-off-by:

bits 16:17 in SD_CTL register refer to stripe control. Added an offset register(AZX_REG_SD_CTL_3B) to have exclusive read/write of corresponding register byte. This helps to avoid unnecessary 32-bit read/write of SD_CTL whenever only stripe or other bits of corresponding byte need to be updated. Also HD audio spec defines SD_CTL as 3 byte register. SD_CTL_STRIPE_MASK(0x3) can be used for stripe control programming and when updating AZX_REG_SD_CTL_3B. Signed-off-by:

Controllers and codecs can support striping of audio out across multiple SDO lines. The number of supported SDO lines can be specific to chip. GCAP register can be read to know the maximum supported SDO lines. snd_hdac_get_stream_stripe_ctl() is exposed to program stripe bits on controller and codec side. stripe value: 0 for 1SDO, 1 for 2SDO, 2 for 4SDO lines, etc., Signed-off-by:

Controllers can support multiple Serial Data Out(SDO) lines, for extended outbound bandwidth, to pump data to all codecs on the link. Codecs can sample data present on SDO. Add verbs AC_VERB_GET_STRIPE_CONTROL and AC_VERB_SET_STRIPE_CONTROL These can be used to program usage of SDO lines for codec. Signed-off-by:
