The + * BR/~D line on the chip is brought high to signal 'command mode', + * where a command byte is sent to select the baudrate of the RS232 + * interface and the pulse length of the IRDA output. When BR/~D + * is brought low, the dongle then changes to the selected baudrate, + * and the RS232 interface is used for data until BR/~D is brought + * high again. The initial speed for the TOIMx323 after RESET is + * 9600 baud. The baudrate for command-mode is the last selected + * baud-rate, or 9600 after a RESET. + * + * The dongle I have (below) adds some extra hardware on the front end, + * but this is mostly directed towards pariasitic power from the RS232 + * line rather than changing very much about how to communicate with + * the TOIM3232. + * + * The protocol to talk to the TOIM4232 chipset seems to be almost + * identical to the TOIM3232 (and the 4232 datasheet is more detailed) + * so this code will probably work on that as well, although I haven't + * tested it on that hardware. + * + * Target dongle variations that might be common: + * + * DTR and RTS function: + * The data sheet for the 4232 has a sample implementation that hooks the + * DTR and RTS lines to the RESET and BaudRate/~Data lines of the + * chip (through line-converters). Given both DTR and RTS would have to + * be held low in normal operation, and the TOIMx232 requires +5V to + * signal ground, most dongle designers would almost certainly choose + * an implementation that kept at least one of DTR or RTS high in + * normal operation to provide power to the dongle, but will likely + * vary between designs. + * + * User specified command bits: + * There are two user-controllable output lines from the TOIMx232 that + * can be set low or high by setting the appropriate bits in the + * high-nibble of the command byte (when setting speed and pulse length). + * These might be used to switch on and off added hardware or extra + * dongle features. + * + * + * Target hardware: IRWave IR320ST-2 + * + * The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic + * TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transciever. + * It uses a hex inverter and some discrete components to buffer and + * line convert the RS232 down to 5V. + * + * The dongle is powered through a voltage regulator, fed by a large + * capacitor. To switch the dongle on, DTR is brought high to charge + * the capacitor and drive the voltage regulator. DTR isn't associated + * with any control lines on the TOIM3232. Parisitic power is also taken + * from the RTS, TD and RD lines when brought high, but through resistors. + * When DTR is low, the circuit might lose power even with RTS high. + * + * RTS is inverted and attached to the BR/~D input pin. When RTS + * is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode. + * RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command + * mode'. + * + * For some unknown reason, the RESET line isn't actually connected + * to anything. This means to reset the dongle to get it to a known + * state (9600 baud) you must drop DTR and RTS low, wait for the power + * capacitor to discharge, and then bring DTR (and RTS for data mode) + * high again, and wait for the capacitor to charge, the power supply + * to stabilise, and the oscillator clock to stabilise. + * + * Fortunately, if the current baudrate is known, the chipset can + * easily change speed by entering command mode without having to + * reset the dongle first. + * + * Major Components: + * + * - Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings + * to IRDA pulse timings + * - 3.6864MHz crystal to drive TOIM3232 clock oscillator + * - DM74lS04M Inverting Hex line buffer for RS232 input buffering + * and level conversion + * - PJ2951AC 150mA voltage regulator + * - Vishay/Temic TFDS4500 SIR IRDA front-end transceiver + * + */ + +#include <linux/module.h> +#include <linux/delay.h> +#include <linux/init.h> + +#include <net/irda/irda.h> + +#include "sir-dev.h" + +static int toim3232delay = 150; /* default is 150 ms */ +module_param(toim3232delay, int, 0); +MODULE_PARM_DESC(toim3232delay, "toim3232 dongle write complete delay"); + +#if 0 +static int toim3232flipdtr = 0; /* default is DTR high to reset */ +module_param(toim3232flipdtr, int, 0); +MODULE_PARM_DESC(toim3232flipdtr, "toim3232 dongle invert DTR (Reset)"); + +static int toim3232fliprts = 0; /* default is RTS high for baud change */ +module_param(toim3232fliptrs, int, 0); +MODULE_PARM_DESC(toim3232fliprts, "toim3232 dongle invert RTS (BR/D)"); +#endif + +static int toim3232_open(struct sir_dev *); +static int toim3232_close(struct sir_dev *); +static int toim3232_change_speed(struct sir_dev *, unsigned); +static int toim3232_reset(struct sir_dev *); + +#define TOIM3232_115200 0x00 +#define TOIM3232_57600 0x01 +#define TOIM3232_38400 0x02 +#define TOIM3232_19200 0x03 +#define TOIM3232_9600 0x06 +#define TOIM3232_2400 0x0A + +#define TOIM3232_PW 0x10 /* Pulse select bit */ + +static struct dongle_driver toim3232 = { + .owner = THIS_MODULE, + .driver_name = "Vishay TOIM3232", + .type = IRDA_TOIM3232_DONGLE, + .open = toim3232_open, + .close = toim3232_close, + .reset = toim3232_reset, + .set_speed = toim3232_change_speed, +}; + +static int __init toim3232_sir_init(void) +{ + if (toim3232delay < 1 || toim3232delay > 500) + toim3232delay = 200; + IRDA_DEBUG(1, "%s - using %d ms delay\n", + toim3232.driver_name, toim3232delay); + return irda_register_dongle(&toim3232); +} + +static void __exit toim3232_sir_cleanup(void) +{ + irda_unregister_dongle(&toim3232); +} + +static int toim3232_open(struct sir_dev *dev) +{ + struct qos_info *qos = &dev->qos; + + IRDA_DEBUG(2, "%s()\n", __FUNCTION__); + + /* Pull the lines high to start with. + * + * For the IR320ST-2, we need to charge the main supply capacitor to + * switch the device on.

First, all interfaces are searched - * for an AudioControl class interface. If found, the config descriptor - * that belongs to the current configuration is searched and - * the HEADER descriptor is found. It contains a list of - * all AudioStreaming and MIDIStreaming devices. This list is then walked, - * and all AudioStreaming interfaces are classified into input and output - * interfaces (according to the endpoint0 direction in altsetting1) (MIDIStreaming - * is currently not supported). The input & output list is then used - * to group inputs and outputs together and issued pairwise to the - * AudioStreaming class parser. Finally, all OUTPUT_TERMINAL descriptors - * are walked and issued to the mixer construction routine. - * - * The AudioStreaming parser simply enumerates all altsettings belonging - * to the specified interface. It looks for AS_GENERAL and FORMAT_TYPE - * class specific descriptors to extract the sample format/sample rate - * data. Only sample format types PCM and PCM8 are supported right now, and - * only FORMAT_TYPE_I is handled. The isochronous data endpoint needs to - * be the first endpoint of the interface, and the optional synchronisation - * isochronous endpoint the second one. - * - * Mixer construction works as follows: The various TERMINAL and UNIT - * descriptors span a tree from the root (OUTPUT_TERMINAL) through the - * intermediate nodes (UNITs) to the leaves (INPUT_TERMINAL). We walk - * that tree in a depth first manner. FEATURE_UNITs may contribute volume, - * bass and treble sliders to the mixer, MIXER_UNITs volume sliders. - * The terminal type encoded in the INPUT_TERMINALs feeds a heuristic - * to determine "meaningful" OSS slider numbers, however we will see - * how well this works in practice. Other features are not used at the - * moment, they seem less often used. Also, it seems difficult at least - * to construct recording source switches from SELECTOR_UNITs, but - * since there are not many USB ADC's available, we leave that for later. - */ - -/*****************************************************************************/ - -#include <linux/kernel.h> -#include <linux/slab.h> -#include <linux/string.h> -#include <linux/timer.h> -#include <linux/sched.h> -#include <linux/smp_lock.h> -#include <linux/module.h> -#include <linux/sound.h> -#include <linux/soundcard.h> -#include <linux/list.h> -#include <linux/vmalloc.h> -#include <linux/init.h> -#include <linux/poll.h> -#include <linux/bitops.h> -#include <asm/uaccess.h> -#include <asm/io.h> -#include <linux/usb.h> - -#include "audio.h" - -/* - * Version Information - */ -#define DRIVER_VERSION "v1.0.0" -#define DRIVER_AUTHOR "Alan Cox <alan@lxorguk.ukuu.org.uk>, Thomas Sailer (sailer@ife.ee.ethz.ch)" -#define DRIVER_DESC "USB Audio Class driver" - -#define AUDIO_DEBUG 1 - -#define SND_DEV_DSP16 5 - -#define dprintk(x) - -/* --------------------------------------------------------------------- */ - -/* - * Linked list of all audio devices... - */ -static struct list_head audiodevs = LIST_HEAD_INIT(audiodevs);
