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