44 * Clients of the HAL call ath_hal_attach to obtain a reference to an ath_hal
45 * structure for use with the device. Hardware-related operations that
46 * follow must call back into the HAL through interface, supplying the
47 * reference as the first parameter.
51 * Bus i/o type definitions. We define a platform-independent
52 * set of types that are mapped to platform-dependent data for
53 * register read/write operations. We use types that are large
54 * enough to hold a pointer; smaller data should fit and only
55 * require type coercion to work. Larger data can be stored
56 * elsewhere and a reference passed for the bus tag and/or handle.

65 * __ahdecl is analogous to _cdecl; it defines the calling
66 * convention used within the HAL. For most systems this
67 * can just default to be empty and the compiler will (should)
68 * use _cdecl. For systems where _cdecl is not compatible this
69 * must be defined. See linux/ah_osdep.h for an example.
76 * Status codes that may be returned by the HAL. Note that
77 * interfaces that return a status code set it only when an
78 * error occurs--i.e. you cannot check it for success.
