| 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. |
