ALSA: hdac: add link pm and ref counting

2016-05-13T10:43:00+00:00

The HDA links can be switched off when not is use, similarly command DMA can be stopped as well. This calls for a reference counting mechanism on the link by it's users to manage the link power. The DMA can be turned off when all links are off For this we add two APIs snd_hdac_ext_bus_link_get snd_hdac_ext_bus_link_put They help users to turn up/down link and manage the DMA as well Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Acked-by: Takashi Iwai Signed-off-by: Mark Brown

ALSA: hdac: add snd_hdac_ext_bus_link_power_up_all

2016-01-10T12:02:47+00:00

We have an API for powering down all links, we need a similar one for powering up links, so add for power up as well Signed-off-by: Jayachandran B Signed-off-by: Subhransu S. Prusty Signed-off-by: Vinod Koul Reviewed-by: Takashi Iwai Signed-off-by: Mark Brown

ALSA: hdac: Add support for hda DMA Resume capability

2016-01-10T12:02:30+00:00

Skylake sports new capability of DMA resume, DRSM where we can resume the DMA. This capability is defined by presence of AZX_DRSM_CAP_ID. If this capability is present, we use this capability. So we add: snd_hdac_ext_stream_drsm_enable() - DMA resume caps snd_hdac_ext_stream_set_dpibr() - set the DMA position snd_hdac_ext_stream_set_lpib() - set the lpib Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Reviewed-by: Takashi Iwai Signed-off-by: Mark Brown

ALSA: hdac: structure definition for ext_dma_params

2015-11-21T13:55:38+00:00

This extends the structure definition of ext_device and adds definition for dma_params which will be used when hdmi codec. Signed-off-by: Subhransu S. Prusty Signed-off-by: Vinod Koul Acked-by: Takashi Iwai Signed-off-by: Mark Brown

ALSA: hdac: Add macro for hda ext devices entry

2015-10-20T08:19:16+00:00

With the new modalias infrastructure support added for hda, create a macro for ext devices similar to legacy to add the device entry. Signed-off-by: Subhransu S. Prusty Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: fix the spbmaxfifo API

2015-08-23T07:43:26+00:00

spbmaxfifo API is actually a query function not a set function so name it snd_hdac_ext_stream_get_spbmaxfifo() Reported-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Add support to enable SPIB for hdac ext stream

2015-08-21T17:28:20+00:00

The drivers need to set the spib and maxfifios values, so add these new APIs snd_hdac_ext_stream_set_spib() and snd_hdac_ext_stream_set_spbmaxfifo() APIs For these APIs we also need to have spib and fifos pointer, so add these to hdac_ext_stream and initialize them at stream init Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: Add snd_hdac_ext_bus_link_power_down_all()

2015-08-21T17:28:18+00:00

New HDA controllers like Skylake sport multiple HDA links, so we need a helper to turn off all the links in one go while suspending the device so add snd_hdac_ext_bus_link_power_down_all() API Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: hdac: add extended device driver registration
