23 Abstract: rt2500usb device specific routines.
24 Supported chipsets: RT2570.
28 * Set enviroment defines for rt2x00.h
30 #define DRV_NAME "rt2500usb"
32 #include <linux/delay.h>
33 #include <linux/etherdevice.h>
34 #include <linux/init.h>
35 #include <linux/kernel.h>
36 #include <linux/module.h>
37 #include <linux/usb.h>
40 #include "rt2x00usb.h"
41 #include "rt2500usb.h"
45 * All access to the CSR registers will go through the methods
46 * rt2500usb_register_read and rt2500usb_register_write.
47 * BBP and RF register require indirect register access,
48 * and use the CSR registers BBPCSR and RFCSR to achieve this.
49 * These indirect registers work with busy bits,
50 * and we will try maximal REGISTER_BUSY_COUNT times to access
51 * the register while taking a REGISTER_BUSY_DELAY us delay
52 * between each attampt. When the busy bit is still set at that time,
53 * the access attempt is considered to have failed,
54 * and we will print an error.
