[alsa-devel] [PATCH v2 00/11] ASoC: hdac: Add hdac generic driver
HDA devices generically can be modelled with DAPM in ASoC.
We would like to create a framework for the HDA devices in ASoC. This will follow HDA standard. This will be registered as generic "virtual" class device (Not implemented in this series). If there is no match found for vendor id and device id, then the class driver will be loaded. For vendor specific devices, vendor quirks will be loaded based on the match. Additional widgets, controls and route will be created in a vendor specific way through vendor ops.
This series adds a framework in ASoC to model HDA codecs. HDA widgets are enumerated and one or multiple DAPM widget(s) are created. Connection list is queried for each widget to identify the connection between two endpoints and modelled using DAPM graph.
Set of event handlers are defined for each widget type. Based on DAPM events required verbs are sent to program codec.
Finally a function is exported to query for the device endpoint configuration to create machine controls.
Features yet to be added: - Optional features of widgets will be added using additional dapm widgets or controls - Pin retasking will be done by adding all possible dapm route map - Class driver to load the generic driver if no match found - Jack detection
changes in v2: - Addressed review comment from Takashi - Moved the widget_list to hdac_ext_device - helper to fill the widget list is now called from hdac_ext_bus_device_init instead of driver probe - Fixed a NULL pointer dereferencing issue - Reorder patch to fix 'auto build test error' - Playback with hs/spk and amic capture now working for rt286 - And some more cleanup and code refactoring to avoid long function definition

Add hdac helpers to enumerate the HDA widgets and fill connection lists for each. During ext device init, these helpers are used to parse the HDA codec for the widgets and cache them in a list.

The macro will be used to identify pins input capability. Based on the capability ASoC driver creates DAPM widget for pin. Also based on input capability widget parsing is done for DAPM graph creation.

This patch adds support to register the hdac driver with the HDA bus and enumerate the driver if a device is found.
It uses the hdac core helper APIs to parse the HDA widgets and identifies the number of mapping dapm widgets to be created. Based on the ADCs and DACs queries the codec dais are allocated and registers with asoc.
The AFG node is power managed through set_bias_level callback. Format is programmed though hw_params dai ops. Stream tag is programmed thorugh the set_tdm_slot callback.

HDA device widgets are mapped to dapm widgets to take advantage of DAPM. Each HDA widget can be mapped to one or multiple dapm widgets based on interface and how it is connected with other widgets.
For example, a PIN widget 2 or 3 dapm widgets are created depending on the capability. A dapm input/out widget is created to represent the input/output capability, a pga widget is created so that pin with retasking capability can be properly represented in a dapm graph and a mux widget for output pin is created, if the connection list has more than one input.

This patch recursively traverses the HDA codec widgets and builds the graph by querying connection list of each.
Only output pin widget and adc widget endpoints can support connection list. So for a playback path query happens from output pin widget end and for a capture path query happens from adc widget end till an input endpoint is found.
