47 * Register access.
48 * All access to the CSR registers will go through the methods
49 * rt73usb_register_read and rt73usb_register_write.
50 * BBP and RF register require indirect register access,
51 * and use the CSR registers BBPCSR and RFCSR to achieve this.
52 * These indirect registers work with busy bits,
53 * and we will try maximal REGISTER_BUSY_COUNT times to access
54 * the register while taking a REGISTER_BUSY_DELAY us delay
55 * between each attampt. When the busy bit is still set at that time,
56 * the access attempt is considered to have failed,
57 * and we will print an error.
