ASoC: SOF: Switch to IPC generic firmware tracing

2022-05-19T15:44:15Z

Introduce new, generic API for firmware tracing with sof_fw_trace_ prefix and switch to use it. At the same time the old IPC3 code can be dropped from trace.c, which is now a generic wrapper for the firmware tracing ops.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

2022-04-19T11:03:39Z

Now that we start having multiple platforms with minor variants, the use of the const qualifier for 'dsp_ops' is starting to be sub-optimal: the structures are copied across platforms, with only a couple of members that differ. This patch removes the const qualifier without any functionality changes, and adds an optional initialization callback. In follow-up patches, the dsp_ops will revisited for Intel HDaudio platforms, with the differences added programmatically over a common baseline.
