This depends on what's idiomatic for the data you need to download - what is the data?
The data could be filter coefficients, or maybe even proprietary
For these it depends; frequently these are (like your existing EQ configuration) included in platform data but it really depends on how they are generated and if they are custom to a particular system (eg, dependant on plastics or particular speakers).
In addition to the platform data, I would like in the future be able to load in data values that are stored in or generated from the user space. Would I use the ALSA interface for this, or would it need to be a separate interface?
binary code image that goes into the chip's memory.
For this use request_firmware() and associated interfaces.
Is it more common to load the firmware from the kernel space? Is there an established mechanism for loading from user space? Thanks.
