49 * All access to the CSR registers will go through the methods
50 * rt2x00usb_register_read and rt2x00usb_register_write.
51 * BBP and RF register require indirect register access,
52 * and use the CSR registers BBPCSR and RFCSR to achieve this.
53 * These indirect registers work with busy bits,
54 * and we will try maximal REGISTER_BUSY_COUNT times to access
55 * the register while taking a REGISTER_BUSY_DELAY us delay
56 * between each attampt. When the busy bit is still set at that time,
57 * the access attempt is considered to have failed,
58 * and we will print an error.
59 * The _lock versions must be used if you already hold the csr_mutex
