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

2.33.0
In preparation for moving the generic DSP support out of ASoC, add
some new logging macros that will be used from the generic code.

From: Charles Keepax <[email protected]>
Checking earlier in the function if a control already exists avoids
superfluous string construction and also prepares for future
refactoring.

2.33.0
This is preparation for moving the generic DSP support out of ASoC.
Passing the firmware as parameters into the power_up functions
simplifies the generic code that will be moved out of wm_adsp.

As preparation for moving the generic DSP support out of ASoC pass the
firmware names used when loading files as parameters as the generic code
can't refer directly to the array specific to wm_adsp. The code
remaining in wm_adsp.c doesn't need to change, it can continue to use
the string arrays directly.

wm_adsp originally provided firmware loading on some audio DSP and was
implemented as an ASoC codec driver. However, the firmware loading now
covers a wider range of DSP cores and peripherals containing them,
beyond just audio. So it needs to be available to non-audio drivers. All
the core firmware loading support has been moved into a new driver
cs_dsp, leaving only the ASoC-specific parts in wm_adsp.

In preparation for moving the generic DSP support out of ASoC, remove
the use of the ALSA specific types for the control type. The use of an
ALSA type was unnecessary, the simplified code is easier to read and
avoids Sparse warnings.

This is preparation for moving the generic DSP support out of ASoC. The

separates the generic and ASoC specific details into separate structures
and functions and renames the generic code named wm_* to cs_*.

sys_config_size is part of the compressed stream support, move it from
what will become generic DSP code so that it remains in ASoC.

2.33.0
From: Charles Keepax <[email protected]>
When parsing a compressed buffer from the firmware the driver currently
open codes reading the firmware coefficient containing the buffer
description. Improve this slightly by using the coefficient read
functions already provided by the wm_adsp driver. It is worth noting
this change requires the running variable to be set before
wm_adsp_buffer_init is called, however this is safe, since its all still
under the power lock and nothing in the compressed code gates itself on
running.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
