Merge series "add driver to support firmware loading on Cirrus Logic DSPs"... 

Merge series "add driver to support firmware loading on Cirrus Logic DSPs" from Simon Trimmer <simont@opensource.cirrus.com>:

This series of patches gradually separates the ASoC specific wm_adsp
code from that required to manage firmware in Cirrus Logic DSPs.

The series starts with renaming, progresses to splitting the
functionality before finally moving the independent functionality into
drivers/firmware so that it can be used by both the existing ASoC
wm_adsp and new non-audio parts.

Charles Keepax (3):
  ASoC: wm_adsp: Move check for control existence
  ASoC: wm_adsp: Switch to using wm_coeff_read_ctrl for compressed
    buffers
  ASoC: wm_adsp: Move sys_config_size to wm_adsp

Simon Trimmer (13):
  ASoC: wm_adsp: Remove use of snd_ctl_elem_type_t
  ASoC: wm_adsp: Cancel ongoing work when removing controls
  ASoC: wm_adsp: Rename generic DSP support
  ASoC: wm_adsp: Introduce cs_dsp logging macros
  ASoC: wm_adsp: Separate some ASoC and generic functions
  ASoC: wm_adsp: Split DSP power operations into helper functions
  ASoC: wm_adsp: Separate generic cs_dsp_coeff_ctl handling
  ASoC: wm_adsp: Move check of dsp->running to better place
  ASoC: wm_adsp: Pass firmware names as parameters when starting DSP
    core
  ASoC: wm_adsp: move firmware loading to client
  ASoC: wm_adsp: Split out struct cs_dsp from struct wm_adsp
  ASoC: wm_adsp: Separate wm_adsp specifics in cs_dsp_client_ops
  firmware: cs_dsp: add driver to support firmware loading on Cirrus
    Logic DSPs
