firmware: cirrus: cs_dsp: Only log list of algorithms in debug build

2023-09-13T17:50:32+00:00

Change the logging of each algorithm from info level to debug level.

On the original devices supported by this code there were typically only
one or two algorithms in a firmware and one or two DSPs so this logging
only used a small number of log lines.

However, for the latest devices there could be 30-40 algorithms in a
firmware and 8 DSPs being loaded in parallel, so using 300+ lines of log
for information that isn't particularly important to have logged.

firmware: cs_dsp: Fix new control name check

2023-08-15T18:23:01+00:00

Before adding a new FW control, its name is checked against
existing controls list. But the string length in strncmp used
to compare controls names is taken from the list, so if beginnings
of the controls are matching,  then the new control is not created.
For example, if CAL_R control already exists, CAL_R_SELECTED
is not created.
The fix is to compare string lengths as well.

ASoC: Merge fixes due to dependencies

So we can apply the tlv320aic3xxx DT conversion.

firmware: cs_dsp: Log correct region name in bin error messages

2023-06-05T14:35:46+00:00

In cs_dsp_load_coeff() region_name should be set in the XM/YM/ZM
cases otherwise any errors will log the region as "Unknown".

While doing this also change one error message that logged the
region type ID to log the region_name instead. This makes it
consistent with other messages in the same function.

firmware: cs_dsp: Log that a bin file was loaded

2023-06-01T11:30:44+00:00

Change the message at the start of bin file loading from
cs_dsp_dbg() to cs_dsp_info() so that there is confirmation
in the kernel log that a bin file was loaded, and the name
of the file.

firmware: cs_dsp: Add a debugfs entry containing control details

2023-04-03T11:15:28+00:00

The file named 'controls' in the DSP's debugfs root contains a
formatted table describing the controls defined within the loaded DSP
firmware, it is of the form

  name: len region:offset addr fwname algid ctltype flags en dirty

Where flags is represented as a character for each flag if set, or '-',
enabled is whether the control is enabled or disabled and dirty is
whether the control value is set in the cache but not the hardware.

firmware: cs_dsp: Support DSPs that don't require firmware download

2023-03-21T12:13:19+00:00

When a DSP can self-boot from ROM it is not necessary to download
firmware during the powering up sequence.

A DSP that required firmware download would fail in a previous
configuration step if firmware was not available.

firmware: cs_dsp: Introduce no_core_startstop for self-booting DSPs

2023-03-21T12:13:17+00:00

There are devices containing Halo Core DSPs that self-boot, cs_dsp is
used to manage the running firmware but the host does not have direct
control over starting and stopping the DSP and so cs_dsp should consider
the DSP to be always running.

firmware: cs_dsp: Switch to using namespaced exports

2022-11-25T14:36:56+00:00

Merge series from Richard Fitzgerald :

Use EXPORT_SYMBOL_NS_GPL() instead of EXPORT_SYMBOL_GPL() and patch the
three drivers that use cs_dsp to add the MODULE_IMPORT_NS().

To make the namespace more specific the KConfig symbol for cs_dsp is
changed from CS_DSP to FW_CS_DSP.

firmware: cs_dsp: Make the exports namespaced

2022-11-25T11:54:00+00:00

Move all the exports into a namespace.
This also adds the MODULE_IMPORT_NS to the 3 drivers that use the
exported functions.
