Kernel audio drivers can be categorised into below folders. asoc - ALSA based drivers, asoc/codecs - codec drivers, ipc - APR IPC communication drivers, dsp - DSP low level drivers/Audio ION/ADSP Loader, dsp/codecs - Native encoders and decoders, soc - SoC based drivers(pinctrl/regmap/soundwire) Restructure drivers to above folder format. Include directories also follow above format. Change-Id: I8fa0857baaacd47db126fb5c1f1f5ed7e886dbc0 Signed-off-by: Laxminath Kasam <lkasam@codeaurora.org>
