23 * Atheros Hardware Access Layer
25 * Clients of the HAL call ath_hal_attach to obtain a reference to an ath_hal
26 * structure for use with the device. Hardware-related operations that
27 * follow must call back into the HAL through interface, supplying the
28 * reference as the first parameter.
31 * Bus i/o type definitions. We define a platform-independent
32 * set of types that are mapped to platform-dependent data for
33 * register read/write operations. We use types that are large
34 * enough to hold a pointer; smaller data should fit and only
35 * require type coercion to work. Larger data can be stored
36 * elsewhere and a reference passed for the bus tag and/or handle.

40 typedef void* HAL_BUS_HANDLE; /* opaque bus i/o handle */
43 * __ahdecl is analogous to _cdecl; it defines the calling
44 * convention used within the HAL. For most systems this
45 * can just default to be empty and the compiler will (should)
46 * use _cdecl. For systems where _cdecl is not compatible this
47 * must be defined. See linux/ah_osdep.h for an example.
54 * Status codes that may be returned by the HAL. Note that
55 * interfaces that return a status code set it only when an
56 * error occurs--i.e. you cannot check it for success.
