[alsa-devel] [PATCH v2 00/10] ASoC: support adding PCM dynamically from topology

[mengdong.lin at intel.com]

From: Mengdong Lin <mengdong.lin at intel.com>

This series allows the topology core to create PCM devices dynamically.
The user can define different DAIs in the topology files for different
versions of firmware, but share a generic platform and machine driver.

A dummy DAI and DAI link can be used to register the soc card and specify
the platform with topology. Then real DAIs are created in platform probing
phase by the topology core, and the machine driver will be notified to create
relavant DAI links.

We tested using topology to create FE DAI/DAI links on Broadwell.

Mengdong Lin (10):
  ASoC: Change the PCM runtime array to a list
  ASoC: Define soc_init_dai_link() to wrap link intialization.
  ASoC: Change 2nd argument of soc_bind_dai_link() to DAI link pointer
  ASoC: Implement DAI links in a list
  ASoC: Add support for dummy DAI links and PCM runtimes
  ASoC: Bind new DAI links after probing components
  ASoC: Support adding a DAI dynamically
  ASoC: topology: Change pass number of DAI smaller than graph
  ASoC: topology: Change stream formats to bitwise flag
  ASOC: topology: Add PCM DAIs dynamically when loading them
