Detailed Description

MOST Base Driver. Contains all attributes and function pointers a MOST Device must provide. The functions are used by higher-level drivers so that they don't need direct PCI access. It increased code readability and abstracts from the real hardware so that a MOST device using the same MOST Transceivers (OS8104 and OS8604) can be accessed without modifying high-level code.

Field Documentation

spinlock_t most_dev::lock

lock access to the struct, also implement some kind of global device lock if needed (such as reading a register, modifying it and writing it back)

struct list_head most_dev::list

list of all devices of a specific category

int most_dev::card_number

the card number, used to register the right character devices.
