Brushkoff. I have 23 * fixed a couple of things. 24 * 25 * (27/May/2004) Ian Abbott 26 * Improved throttling code, mostly stolen from the WhiteHEAT driver. 27 * 28 * (26/Mar/2004) Jan Capek 29 * Added PID's for ICD-U20/ICD-U40 - incircuit PIC debuggers from CCS Inc. 30 * 31 * (09/Feb/2004) Ian Abbott 32 * Changed full name of USB-UIRT device to avoid "/" character. 33 * Added FTDI's alternate PID (0x6006) for FT232/245 devices. 34 * Added PID for "ELV USB Module UO100" from Stefan Frings. 35 * 36 * (21/Oct/2003) Ian Abbott 37 * Renamed some VID/PID macros for Matrix Orbital and Perle Systems 38 * devices. Removed Matrix Orbital and Perle Systems devices from the 39 * 8U232AM device table, but left them in the FT232BM table, as they are 40 * known to use only FT232BM. 41 * 42 * (17/Oct/2003) Scott Allen 43 * Added vid/pid for Perle Systems UltraPort USB serial converters 44 * 45 * (21/Sep/2003) Ian Abbott 46 * Added VID/PID for Omnidirectional Control Technology US101 USB to 47 * RS-232 adapter (also rebadged as Dick Smith Electronics XH6381). 48 * VID/PID supplied by Donald Gordon. 49 * 50 * (19/Aug/2003) Ian Abbott 51 * Freed urb's transfer buffer in write bulk callback. 52 * Omitted some paranoid checks in write bulk callback that don't matter. 53 * Scheduled work in write bulk callback regardless of port's open count. 54 * 55 * (05/Aug/2003) Ian Abbott 56 * Added VID/PID for ID TECH IDT1221U USB to RS-232 adapter. 57 * VID/PID provided by Steve Briggs. 58 * 59 * (23/Jul/2003) Ian Abbott 60 * Added PIDs for CrystalFontz 547, 633, 631, 635, 640 and 640 from 61 * Wayne Wylupski. 62 * 63 * (10/Jul/2003) David Glance 64 * Added PID for DSS-20 SyncStation cradle for Sony-Ericsson P800. 65 * 66 * (27/Jun/2003) Ian Abbott 67 * Reworked the urb handling logic. We have no more pool, but dynamically 68 * allocate the urb and the transfer buffer on the fly. In testing this 69 * does not incure any measurable overhead. This also relies on the fact 70 * that we have proper reference counting logic for urbs. I nicked this 71 * from Greg KH's Visor driver. 72 * 73 * (23/Jun/2003) Ian Abbott 74 * Reduced flip buffer pushes and corrected a data length test in 75 * ftdi_read_bulk_callback. 76 * Defererence pointers after any paranoid checks, not before. 77 * 78 * (21/Jun/2003) Erik Nygren 79 * Added support for Home Electronics Tira-1 IR tranceiver using FT232BM chip. 80 * See <http://www.home-electro.com/tira1.htm>. Only operates properly 81 * at 100000 and RTS-CTS, so set custom divisor mode on startup. 82 * Also force the Tira-1 and USB-UIRT to only use their custom baud rates. 83 * 84 * (18/Jun/2003) Ian Abbott 85 * Added Device ID of the USB relais from Rudolf Gugler (backported from 86 * Philipp G�hring's patch for 2.5.x kernel). 87 * Moved read transfer buffer reallocation into startup function. 88 * Free existing write urb and transfer buffer in startup function. 89 * Only use urbs in write urb pool that were successfully allocated. 90 * Moved some constant macros out of functions. 91 * Minor whitespace and comment changes. 92 * 93 * (12/Jun/2003) David Norwood 94 * Added support for USB-UIRT IR tranceiver using 8U232AM chip. 95 * See <http://home.earthlink.net/~jrhees/USBUIRT/index.htm>. Only 96 * operates properly at 312500, so set custom divisor mode on startup. 97 * 98 * (12/Jun/2003) Ian Abbott 99 * Added Sealevel SeaLINK+ 210x, 220x, 240x, 280x vid/pids from Tuan Hoang 100 * - I've eliminated some that don't seem to exist! 101 * Added Home Electronics Tira-1 IR transceiver pid from Chris Horn 102 * Some whitespace/coding-style cleanups 103 * 104 * (11/Jun/2003) Ian Abbott 105 * Fixed unsafe spinlock usage in ftdi_write 106 * 107 * (24/Feb/2003) Richard Shooter 108 * Increase read buffer size to improve read speeds at higher baud rates 109 * (specifically tested with up to 1Mb/sec at 1.5M baud) 110 * 111 * (23/Feb/2003) John Wilkins 112 * Added Xon/xoff flow control (activating support in the ftdi device) 113 * Added vid/pid for Videonetworks/Homechoice (UK ISP) 114 * 115 * (23/Feb/2003) Bill Ryder 116 * Added matrix orb device vid/pids from Wayne Wylupski 117 * 118 * (19/Feb/2003) Ian Abbott 119 * For TIOCSSERIAL, set alt_speed to 0 when ASYNC_SPD_MASK value has 120 * changed to something other than ASYNC_SPD_HI, ASYNC_SPD_VHI, 121 * ASYNC_SPD_SHI or ASYNC_SPD_WARP. Also, unless ASYNC_SPD_CUST is in 122 * force, don't bother changing baud rate when custom_divisor has changed. 123 * 124 * (18/Feb/2003) Ian Abbott 125 * Fixed TIOCMGET handling to include state of DTR and RTS, the state 126 * of which are now saved by set_dtr() and set_rts(). 127 * Fixed improper storage class for buf in set_dtr() and set_rts(). 128 * Added FT232BM chip type and support for its extra baud rates (compared 129 * to FT8U232AM). 130 * Took account of special case divisor values for highest baud rates of 131 * FT8U232AM and FT232BM. 132 * For TIOCSSERIAL, forced alt_speed to 0 when ASYNC_SPD_CUST kludge used, 133 * as previous alt_speed setting is now stale. 134 * Moved startup code common between the startup routines for the 135 * different chip types into a common subroutine. 136 * 137 * (17/Feb/2003) Bill Ryder 138 * Added write urb buffer pool on a per device basis 139 * Added more checking for open file on callbacks (fixed OOPS) 140 * Added CrystalFontz 632 and 634 PIDs 141 * (thanx to CrystalFontz for the sample devices - they flushed out 142 * some driver bugs) 143 * Minor debugging message changes 144 * Added throttle, unthrottle and chars_in_buffer functions 145 * Fixed FTDI_SIO (the original device) bug 146 * Fixed some shutdown handling 147 * 148 * 149 * 150 * 151 * (07/Jun/2002) Kuba Ober 152 * Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor 153 * function. It was getting too complex. 154 * Fix the divisor calculation logic which was setting divisor of 0.125 155 * instead of 0.5 for fractional parts of divisor equal to 5/8, 6/8, 7/8. 156 * Also make it bump up the divisor to next integer in case of 7/8 - it's 157 * a better approximation. 158 * 159 * (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch 160 * Not tested by me but it doesn't break anything I use. 161 * 162 * (04/Jan/2002) Kuba Ober 163 * Implemented 38400 baudrate kludge, where it can be substituted with other 164 * values. That's the only way to set custom baudrates. 165 * Implemented TIOCSSERIAL, TIOCGSERIAL ioctl's so that setserial is happy. 166 * FIXME: both baudrate things should eventually go to usbserial.c as other 167 * devices may need that functionality too. Actually, it can probably be 168 * merged in serial.c somehow - too many drivers repeat this code over 169 * and over. 170 * Fixed baudrate forgetfulness - open() used to reset baudrate to 9600 every time. 171 * Divisors for baudrates are calculated by a macro. 172 * Small code cleanups. Ugly whitespace changes for Plato's sake only ;-]. 173 * 174 * (04/Nov/2001) Bill Ryder 175 * Fixed bug in read_bulk_callback where incorrect urb buffer was used. 176 * Cleaned up write offset calculation 177 * Added write_room since default values can be incorrect for sio 178 * Changed write_bulk_callback to use same queue_task as other drivers 179 * (the previous version caused panics) 180 * Removed port iteration code since the device only has one I/O port and it 181 * was wrong anyway. 182 * 183 * (31/May/2001) gkh 184 * Switched from using spinlock to a semaphore, which fixes lots of problems. 185 * 186 * (23/May/2001) Bill Ryder 187 * Added runtime debug patch (thanx Tyson D Sawyer). 188 * Cleaned up comments for 8U232 189 * Added parity, framing and overrun error handling 190 * Added receive break handling. 191 * 192 * (04/08/2001) gb 193 * Identify version on module load. 194 * 195 * (18/March/2001) Bill Ryder 196 * (Not released) 197 * Added send break handling. (requires kernel patch too) 198 * Fixed 8U232AM hardware RTS/CTS etc status reporting. 199 * Added flipbuf fix copied from generic device 200 * 201 * (12/3/2000) Bill Ryder 202 * Added support for 8U232AM device. 203 * Moved PID and VIDs into header file only. 204 * Turned on low-latency for the tty (device will do high baudrates) 205 * Added shutdown routine to close files when device removed. 206 * More debug and error message cleanups. 207 * 208 * (11/13/2000) Bill Ryder 209 * Added spinlock protected open code and close code. 210 * Multiple opens work (sort of - see webpage mentioned above). 211 * Cleaned up comments. Removed multiple PID/VID definitions. 212 * Factorised cts/dtr code 213 * Made use of __FUNCTION__ in dbg's 214 * 215 * (11/01/2000) Adam J. Richter 216 * usb_device_id table support 217 * 218 * (10/05/2000) gkh 219 * Fixed bug with urb->dev not being set properly, now that the usb 220 * core needs it. 221 * 222 * (09/11/2000) gkh 223 * Removed DEBUG #ifdefs with call to usb_serial_debug_data 224 * 225 * (07/19/2000) gkh 226 * Added module_init and module_exit functions to handle the fact that this 227 * driver is a loadable module now. 228 * 229 * (04/04/2000) Bill Ryder 230 * Fixed bugs in TCGET/TCSET ioctls (by removing them - they are 231 * handled elsewhere in the tty io driver chain). 232 * 233 * (03/30/2000) Bill Ryder 234 * Implemented lots of ioctls 235 * Fixed a race condition in write 236 * Changed some dbg's to errs 237 * 238 * (03/26/2000) gkh 239 * Split driver up into device specific pieces. 240 * 241 */ 242 243 /* Bill Ryder - bryder@sgi.com - wrote the FTDI_SIO implementation */ 244 /* Thanx to FTDI for so kindly providing details of the protocol required */ 245 /* to talk to the device */ 246 /* Thanx to gkh and the rest of the usb dev group for all code I have assimilated :-) */ 247 248 #include <linux/config.h> 249 #include <linux/kernel.h> 250 #include <linux/errno.h> 251 #include <linux/init.h> 252 #include <linux/slab.h> 253 #include <linux/tty.h> 254 #include <linux/tty_driver.h> 255 #include <linux/tty_flip.h> 256 #include <linux/module.h> 257 #include <linux/spinlock.h> 258 #include <asm/uaccess.h> 259 #include <linux/usb.h> 260 #include <linux/serial.h> 261 #include "usb-serial.h" 262 #include "ftdi_sio.h" 263 264 /* 265 * Version Information 266 */ 267 #define DRIVER_VERSION "v1.4.1" 268 #define DRIVER_AUTHOR "Greg Kroah-Hartman <greg@kroah.com>, Bill Ryder <bryder@sgi.com>, Kuba Ober <kuba@mareimbrium.org>" 269 #define DRIVER_DESC "USB FTDI Serial Converters Driver" 270 271 static int debug; 272 273 static struct usb_device_id id_table_sio [] = { 274 { USB_DEVICE(FTDI_VID, FTDI_SIO_PID) }, 275 { } /* Terminating entry */ 276 }; 277 278 /* 279 * The 8U232AM has the same API as the sio except for: 280 * - it can support MUCH higher baudrates; up to: 281 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz 282 * o 230400 at 12MHz 283 * so .. 8U232AM's baudrate setting codes are different 284 * - it has a two byte status code. 285 * - it returns characters every 16ms (the FTDI does it every 40ms) 286 * 287 * the bcdDevice value is used to differentiate FT232BM and FT245BM from 288 * the earlier FT8U232AM and FT8U232BM.
