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. | |

50 | * If the usb_cache_mutex is already held then the _lock variants must |
51 | * be used instead. | |
