Hi,
ALSA firewire-motu driver becomes to support more models since its first commit 2017. As a result, the original structure for generation-dependent protocol is not suitable for differences between models in some cases.
This patchset is for refactoring the driver to obsolete the protocol structure. Some helper functions are added with condition statement for protocol version so that the function calls protocol-dependent function. Instead of the protocol structure, specification structure is used to represent model information and to choose model-dependent operation so that it's easy to handle model-dependent quirks.
Additionally, this patchset changes the way to calculate the number of chunks in data block. Current implementation calculates by the fixed number of analog input/output ports and flags in the specification structure. Although the flags can represent any physical input/output of the model, it's difficult to debug for supported model and to add support new models, especially for model-dependent quirks. This patchset adds each table for the fixed number of chunks of each model. The calculation is just done for differed part of chunks.
