Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

Document change notification HDA040-A for the Intel High Definition Audio 1.0a specification introduces a Device Select verb for Digital Display Pin Widgets that are multi-stream capable. This verb selects a Device Entry that is used by subsequent Pin Widget verbs. Once the Device Entry is selected, all subsequent Pin Widget verbs controlling the sink device will be directed to the selected Device Entry until the Device Select verb is updated with a new value. These Pin Widget verbs include: * Connection Select * Get Connection List Entry * Amplifier Gain/Mute * Power State * Pin Widget Control * ELD Data * DIP-Size * DIP-Index * DIP-Data * DIP-XmitCtrl * Content Protection Control * ASP Channel Mapping This patch adds calls to snd_hda_set_dev_select() to direct each of these Pin Widget control verbs to the correct Device Entry.

GK104+ NVIDIA codecs support DP-MST audio. These codecs have 4 output converters and 4 pin widgets, with 4 device entries per pin widget for a total of 16 device entries. This patch moves the existing patch_nvhdmi() definition to patch_nvhdmi_legacy(), used by pre-GK104 NVIDIA codecs. Redefine patch_nvhdmi() to enable DP-MST support by setting codec->dp_mst and spec->dyn_pcm_assign. Introduce fresh logic for dynamic pcm assignment, making sure that new pcm assignments are compatible with the legacy static per_pin-pmc assignment that existed in the days before DP-MST.
