Some systems use older firmware which does not support newer commands which are used to enable external boost. For those systems, we can workaround this by writing the registers directly.
We can use the firmware version, stored inside cs_dsp, to determine whether or not the command is supported. To achieve this, it requires a cleanup in the api, to pass the cs_dsp struct into the function.
We can also remove the redundant boolean firmware_running from the HDA driver, and use the equivalent state inside cs_dsp.
So those are fixes needed for 6.6 kernel? Or they are something new?
This chain is based on Mark's branch, since the api change was made to the function in sound/soc/codecs/cs35l41-lib.c.
I'd need a PR from Mark before applying those, then.
thanks,
