New subject: [PATCH v4 01/11] Revert "ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro"

This reverts commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f.

I've explained that optional FireWire card for d.2 is also built-in to d.2 Pro, however it's wrong. The optional card uses DM1000 ASIC and has 'Mackie DJ Mixer' in its model name of configuration ROM. On the other hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC and has 'd.Pro' in its model name according to manuals and user experiences. The former card is not the card for d.2 Pro. They are similar in appearance but different internally.

New subject: [PATCH v4 02/11] ALSA: firewire-lib/motu: use int type for the value of bitwise OR with enumerator-constant

It brings some inconvenience in practice to use enumerated type for variable to which bitwise OR with enumerator constant is assigned.

This commit replaces declarations of enumerated type with int type.

New subject: [PATCH v4 03/11] ALSA: oxfw: code refactoring for existent device entry with specifier_id and version

All of the devices known to be based on OXFW ASICs have the same layout of configuration ROM, in which unit directory includes vendor, model, specifier_id and version immediate values. Especially, the pair of specifier_id and version is fixed to represent AV/C general protocol.

This commit refactors device entries to fulfil with these 4 elements.

New subject: [PATCH v4 07/11] ALSA: oxfw: add comment for the type of ASICs

ALSA OXFW supports two types of ASICS; OXFW970 and OXFW971. The former is known to have a quirk we call 'jumbo payload' that some isochronous cycles are skipped to transfer isochronous packets during handling asynchronous transaction. The quirk seems to correspond to firmware initially delivered by Oxford Semiconductor since the quirk is not confirmed for Mackie Onyx Satellite in which the revised firmware is available. The quirk is not confirmed in the latter.

This commit adds code comment to describe the quirk.
