[alsa-devel] [PATCH 00/30] ASoC: hdac_hdmi: Add support to enable MST audio

[jeeja.kp at intel.com]

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

Display port 1.2 introduces new capability Multi-stream transport (MST)
which will allow multiple stream to route to single display port where
multiple monitors are connected. Multiple monitors will be connected by
a MST Hub or a monitor capable of daisy-chaining.

With MST support, a pin can support multiple ports and on each port a
monitor can be connected.

This patch series enables DP MST Audio by extending the current design
from pin to port.
o With MST, pin mux for CVT selection will be used to select CVT for
pin-port instead of pin. So create the pin mux accordingly.

o Pin is marked as MST capable when connect event reports pipe as valid.
if pipe is -1, then pin is not MST capable and default to port 0.
if pipe is valid, then pin is MST capable and port = pipe.

o For MST capable pin, select the device entry before configuring the pin
widget verbs controlling the sink device operations.

o Add support to handle multiple Port mapped to same converter by creating
as port list in pcm and report jack event based on the no of ports 
connected/disconnected .

o i915 acomp APIs are now used to read the ELD info and support is extended
for MST port as well.

o Configure port/pin/audio infoframe in widget event handlers for dynamic
routing when monitor is connected/disconnected instead of DAI ops. 

o Use set_tdm slot to set the stream tag instead of dai params and store it
in pcm context and use this in configuring the converter in widget event
handler.

o Use pin widget to represent the output to enable/disable path when a device
is connected/disconnected. Added API to create the pin widget and this will be
called by the machine driver after jack creation.

o Add channel map support for bxt machine.

o Move from snd_jack to ASOC jack framework, create the jack in machine driver.

o Create port pin widget to enable and disable the path dynamically when a jack
is connected/disconnected.

Note: This patch series has dependency on the series
