47 * All access to the CSR registers will go through the methods
48 * rt2500usb_register_read and rt2500usb_register_write.
49 * BBP and RF register require indirect register access,
50 * and use the CSR registers BBPCSR and RFCSR to achieve this.
51 * These indirect registers work with busy bits,
52 * and we will try maximal REGISTER_BUSY_COUNT times to access
53 * the register while taking a REGISTER_BUSY_DELAY us delay
54 * between each attampt. When the busy bit is still set at that time,
55 * the access attempt is considered to have failed,
56 * and we will print an error.
