23 Abstract: Data structures for the rt2x00pci module.
32 * This variable should be used with the
33 * pci_driver structure initialization.
35 #define PCI_DEVICE_DATA(__ops) .driver_data = (kernel_ulong_t)(__ops)
39 * Some registers require multiple attempts before success,
40 * in those cases REGISTER_BUSY_COUNT attempts should be
41 * taken with a REGISTER_BUSY_DELAY interval.
43 #define REGISTER_BUSY_COUNT 5
44 #define REGISTER_BUSY_DELAY 100
