Vaibhav Agarwal d3d2af51f9 greybus: Audio: Add skeleton code for GB virtual codec driver ... This patch adds gb-codec driver with static information for DAPM widgets, controls & dapm_routes. Including some changes in kernel code(machine driver): - Able to register codec and glue it with existing sound card successfully. - Able to view & modify mixer controls: (volume/mute[left/right][input/output]) - Able to view DAPM widgets registered via /debug interface. - Able to establish DAPM path for playback. Since, FE<->BE path not yet verified with default jetson build, registering GB DAI as normal DAI link to verify GB virtual codec specific DAPM path.
