39 * Register access.
40 * All access to the CSR registers will go through the methods
41 * rt2500usb_register_read and rt2500usb_register_write.
42 * BBP and RF register require indirect register access,
43 * and use the CSR registers BBPCSR and RFCSR to achieve this.
44 * These indirect registers work with busy bits,
45 * and we will try maximal REGISTER_BUSY_COUNT times to access
46 * the register while taking a REGISTER_BUSY_DELAY us delay
47 * between each attampt. When the busy bit is still set at that time,
48 * the access attempt is considered to have failed,
49 * and we will print an error.

51 * be used instead.
