This patch adds support toi APR bus (Asynchronous Packet Router) driver. ARP driver is made as a bus driver so that the apr devices can added removed more dynamically depending on the state of the services on the dsp. APR is used for communication between application processor and QDSP to use services on QDSP like Audio and others.

From: Srinivas Kandagatla srinivas.kandagatla@linaro.org

This patch adds basic support to Q6 ASM (Audio Stream Manager) module on Q6DSP. ASM supports up to 8 concurrent streams. each stream can be setup as playback/capture. ASM provides top control functions like Pause/flush/resume for playback and record. ASM can Create/destroy encoder, decoder and also provides POPP dynamic services.

This patch adds support to basic features to allow hdmi playback.
