41 * All access to the CSR registers will go through the methods
42 * rt2x00pci_register_read and rt2x00pci_register_write.
43 * BBP and RF register require indirect register access,
44 * and use the CSR registers BBPCSR and RFCSR to achieve this.
45 * These indirect registers work with busy bits,
46 * and we will try maximal REGISTER_BUSY_COUNT times to access
47 * the register while taking a REGISTER_BUSY_DELAY us delay
48 * between each attampt. When the busy bit is still set at that time,
49 * the access attempt is considered to have failed,
50 * and we will print an error.
