From: "Lu, Han" han.lu@intel.com
1. Refactoring alsa process to make structure simpler and cleaner, use general functions and unified return value for convenience of maintaining; 2. Add tinyalsa support, user can choose tinyalsa with "configure --enable-alsabat-backend-tiny" option. By default ALSA lib is used. The intention is for alsabat to run on tinyalsa platforms such as Android and some IoT devices.
changes on v3: 1. use option "--enable-alsabat-backend-tiny" instead of "--enable-tinyalsa" to avoid ambiguous. 2. fix inconsistent in man page and configure.ac. changes on v2: 1. add more description to explain the purpose of each patch. 2. use configure option to select tinyalsa, rather than auto detect environment and decide.
Lu, Han (6): alsabat: refactoring alsa capture thread alsabat: use general function for wav header update alsabat: clean return value for playback and capture threads alsabat: use general data generator function alsabat: move alsa process to a single block alsabat: add tinyalsa support
