2016-02-17ASoC: hdac_hdmi: Remove 'edev' NULL checkFabio Estevam1-3/+0
Commit 4a3478debf36 ("ASoC: hdac_hdmi: Add jack reporting") leads to the following Smatch complaint: sound/soc/codecs/hdac_hdmi.c:971 hdac_hdmi_present_sense() warn: variable dereferenced before check 'edev' (see line 967) As explained by Subhransu S. Prusty: "This NULL check is not required, can be removed. edev object is expected to be present when the present_sense is called. This is called from places where this edev object is already available." So remove the evdev NULL check.

2016-02-15ASoC: hdac_hdmi: Enable playback on all enumerated portsSubhransu S. Prusty1-42/+132
Last patch added infrastructure to render over all the ports, PCM<->cvt<- pin mapping and user selection of controls. But we still have restriction of playback on the default port alone, so remove that. This patch removes the hardcoding of cvt<->pin map from the dai. Cvt and pin for a dai are now derived from the already stored pcm list of device opened. We query connection list of a pin from codec to validate the cvt<->pin map. If connection list returns zero, then monitor is not connected so fail playback. Signed-off-by: Subhransu S.

2016-02-15ASoC: hdac_hdmi: Add jack reportingJeeja KP1-3/+157
Jack is created based on pcm devices enumerated, so we will create Jack as "HDMI/DP, pcm=x Jack". This style is expected by current usermode like PulseAudio and CRAS. This patch exports an API which can be used to register Jack based on PCM. This API also establishes the map between PCM and cvt. Further cvt to pin mapping is established with the help of usermode selection based on the board topology. During device probe as the PCMs may not be registered, initial pin sense don't report jack events. So, first time jack reporting is done during user selection of mux control.

2016-02-15ASoC: hdac_hdmi: Create widget/route based on nodes enumeratedSubhransu S. Prusty1-22/+219
In skylake, HDMI codec enumerates 3 pins and 3 cvts. Stream can be routed from any cvt to any pin based on the connection list queried from the pin. This patch removes the static modelling of widget/route and creates it dynamically based on the codec widgets enumerated. Mux widgets are added to represent the map between a cvt and pin. Ideally the mux widgets should be created based on the connection list queried from the pin widget. But due to HW behavior, if an external display is not connected on a port, querying the connection list returns zero. So create mux widgets to map all the cvt to all pins. At runtime, playback support on a pin can be verified based on the connection list query. Few function in driver have additional arguments now to support this. Signed-off-by: Subhransu S.

2016-02-15ASoC: hdac_hdmi: create dais based on number of cvtsSubhransu S. Prusty1-32/+91
After enabling all pins/cvts, Skylake HDMI codec enumerates 3 converters. Three independent streams can be supported with 3 cvts. This patch removes the static dai creation and creates dais based on the number of cvts queried. Signed-off-by: Subhransu S.

2016-02-15ASoC: hdac_hdmi: Enable DP1.2 and all converters/pinsSubhransu S. Prusty1-0/+43
Skylake supports 3 pin and 3 converter widgets. But by default only one converter and pin widget are enabled. In skylake platform the DP port is on a different port which is not enabled by default. To enable playback on DP port, enable all pin and converter widget by sending a vendor VERB for a vendor widget to set required bits. As we are enabling the DP support enable the DP1.2 feature as well. Enabling DP1.2 and all widget changes are copied from patch_hdmi.c. Signed-off-by: Subhransu S.

2016-02-15ASoC: hdac_hdmi: Add hotplug notification and read ELDSubhransu S. Prusty1-6/+211
This patch uses i915 component framework to register for hotplug notification. In the hotplug notification, driver reads pin sense and ELD by sending PIN_SENSE and ELD verbs over HDA bus. Once it identifies valid pin sense and valid ELD, store the ELD into the corresponding pin map buffer. Also read the monitor present sense during resume and ignore the ELD notify from graphics during PM as is done in legacy hda, commit 8ae743e82f0b ("ALSA: hda - Skip ELD notification during system suspend") Signed-off-by: Subhransu S.

A recent rework removed the only user of the hdac_hdmi_query_pin_connlist function, so we now get a warning when building the hdac_hdmi driver: hdac_hdmi.c:313:12: warning: 'hdac_hdmi_query_pin_connlist' defined but not used [-Wunused-function] This removes the function, which makes the file build cleanly again.

2016-01-08ASoC: hdac_hdmi: Use list to add pins and convertersSubhransu S. Prusty1-48/+106
Future platforms may have a different set of pins/converters. So use lists to add pins and converters based on enumeration. Also it may be required to connect any converter to any pin dynamically as per different use cases (for example DP is connected to pin 6 on skylake board). So this will help in dynamically select and route. Fix the dai map as well to use the pin/cvt from list. Not enabling all dai maps for now. Signed-off-by: Subhransu S.
