[PATCH 00/16] ASoC: hdac_hdmi: Enable MST audio

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

With the patch series "ASoC: hdmi: Preparatory work to support MST audio",
the design is extended from pin to port mapping to handle MST usecases.

A pin is MST capable if pipe is valid value (i.e. not -1) in the notify
callback. If pipe = -1, default port is 0 else port = pipe. A MST capable
pin widget is programmed by first sending a verb to select the device/port
and then the actual verb is sent to program the widget.

This patch series enables MST Audio by configuring MST capable pins and
extended the jack handling to report event for ports. Now the jack events
are based on port connect/disconnect. The design is also extended to support
mapping of multiple port to a single converter.

Now with the introduction of multiple ports with a single pin, a pin widget
is created to enable/disable path based on device connection. Required
machine driver changes are done to handle this change.

Also use the ASoC jack instead of snd_jack framework to creates jacks in
the machine driver.

Note: This patch series has dependency on the series
"ASoC: hdmi: Preparatory work to support MST audio"

[PATCH 01/16] ASoC: hdac_hdmi: Add MST verb support

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

To support DP MST audio, new pin verbs/params are added. This patch
adds helper functions to do following:
o To set a specific port
o To get the currently selected port
o To get the length of port.

[PATCH 02/16] ASoC: hdac_hdmi: Handle MST pin jack detection at boot/resume

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

The ELD notification can be received asynchronously from the graphics
side and this may happen just at the moment the sound driver is
initializing and notification will be missed. Similarly at system
resume, the notification is ignored as the  ELD and connection states
are updated in anyway at the end of the resume.
So check the jack status in boot/resume by querying the port presence
based on pin caps and report the jack status.

[PATCH 03/16] ASoc: hdac_hdmi: Configure pin verbs for MST

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

To enable stream on a specific port of a MST capable pin, the port
needs to be selected before we configure the pin widget verb.

When port is selected, all the pin widget verb controlling the sink
device operation will be directed to selected port. So add port
selection before configuring the pin widget verb.

[PATCH 04/16] ASoC: hdac_hdmi: Add support for multiple ports to a PCM

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

Since we have the MST feature enabled and Pin-Port mux for user to
select the converter routing, multiple port mapping to same converter
needs to be supported.

To support multiple port mapped to same converter following changes are
done for this:.
o Add port list to pcm, so that multiple ports can be mapped to a PCM.
o Jack reporting in case where multiple port are attached to same PCM.
o Change hdac_hdmi_get_port_from_cvt(), channel_map, remove functions
to parse through all ports mapped to same the PCM.

[PATCH 12/16] ASoC: Intel: Skylake: Add jack port initialize in rt286 machine

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

After the pcm jack is created, create and initialize the pin switch
widget for each port. Pin switch is to enable/disable the pin when
monitor is connected/disconnected.
