[PATCH v3 0/4] ASoC: Intel: Skylake - Add IPC routines

[Vinod Koul <vinod.koul@intel.com>]

The SKL aDSP needs to send and receive IPCs to and from aDSP. To aid this we
add IPC and aDSP management routines as a library for driver to use. For
most of IPC handling we use the common IPC Intel code in place and add the
messaging and message parsing bits on top.

First 2 patches are against common IPC code and can be applied independently
Last two add IPC handling and aDSP management routines

v3 changes:
 - sst_dsp_register_poll uses opportunistic polling and polls for first few
   instances using mdelay and later sleeps
 - s/skl_ipc_reply_find_msg/skl_ipc_reply_get_msg
 - return IRQ_NONE when interrupt in not handled
 - removed trace_printk and superfluous cast to/from void *

Subhransu S. Prusty (4):
  ASoC: Intel: Add helper to poll register for DSP status
  ASoC: Intel: Add helper to update register bits with attr RWC
  ASoC: Intel: Add Skylake IPC library
  ASoC: Intel: Add DSP init and boot up functionality for SKL
