ASoC: SOF: Abstractions for top-level IPC ops

Browse Source 
Merge series from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:

This series is continuation of the IPC abstraction in the SOF driver in
preparation for supporting the new IPC supported by the SOF firmware.
It introduces abstraction for top-level IPC ops for sending/receiving
regular and large IPC's.

Peter Ujfalusi (15):
  ASoC: SOF: Add helper function to prepare and send an IPC message
  ASoC: SOF: Add high level IPC IO callback definitions to ipc_ops
  ASoC: SOF: ipc3: Implement the tx_msg IPC ops
  ASoC: SOF: ipc3: Use sof_ipc3_tx_msg() internally for message sending
  ASoC: SOF: ipc3: Implement the set_get_data IPC ops
  ASoC: SOF: ipc3: Implement the get_reply IPC ops
  ASoC: SOF: ipc3: Implement rx_msg IPC ops
  ASoC: SOF: ipc: Separate the ops checks by functions/topics
  ASoC: SOF: ipc: Add check for mandatory IPC message handling ops
  ASoC: SOF: ipc: Use the get_reply ops in snd_sof_ipc_get_reply()
  ASoC: SOF: ipc: Switch over to use the tx_msg and set_get_data ops
  ASoC: SOF: ipc: Switch over to use the rx_msg ops
  ASoC: SOF: Add widget_kcontrol_setup control ops for IPC3
  ASoC: SOF: sof-audio: Use the widget_kcontrol_setup ops for kcontrol
    set up
  ASoC: SOF: ipc: Move the ipc_set_get_comp_data() local to ipc3-control
