V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder
It took three core maintainers, over four years of work, eight new i2c
modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced
VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding
API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac
support from Axel Thimm, (hardware) support from Hauppauge, support and
assistance from the v4l-dvb people and the many, many users of ivtv to
finally make it possible to merge this driver into the kernel.
Thank you all!

Older ivtv versions used i2c-algo-bit, + which whilst fine under most circumstances, had trouble with the Zilog + CPU on the PVR-150 which handles IR functions (occasional inability to + communicate with the chip until it was reset) and also with the i2c + bus being completely unreachable when multiple PVR cards were present. + + The implementation is very similar to i2c-algo-bit, but there are enough + subtle differences that the two are hard to merge. The general strategy + employed by i2c-algo-bit is to use udelay() to implement the timing + when putting out bits on the scl/sda lines. The general strategy taken + here is to poll the lines for state changes (see ivtv_waitscl and + ivtv_waitsda). In addition there are small delays at various locations + which poll the SCL line 5 times (ivtv_scldelay). I would guess that + since this is memory mapped I/O that the length of those delays is tied + to the PCI bus clock. There is some extra code to do with recovery + and retries. Since it is not known what causes the actual i2c problems + in the first place, the only goal if one was to attempt to use + i2c-algo-bit would be to try to make it follow the same code path. + This would be a lot of work, and I'm also not convinced that it would + provide a generic benefit to i2c-algo-bit. Therefore consider this + an engineering solution -- not pretty, but it works. + + Some more general comments about what we are doing: + + The i2c bus is a 2 wire serial bus, with clock (SCL) and data (SDA) + lines. To communicate on the bus (as a master, we don't act as a slave), + we first initiate a start condition (ivtv_start). We then write the + address of the device that we want to communicate with, along with a flag + that indicates whether this is a read or a write. The slave then issues + an ACK signal (ivtv_ack), which tells us that it is ready for reading / + writing. We then proceed with reading or writing (ivtv_read/ivtv_write), + and finally issue a stop condition (ivtv_stop) to make the bus available + to other masters. + + There is an additional form of transaction where a write may be + immediately followed by a read. In this case, there is no intervening + stop condition. (Only the msp3400 chip uses this method of data transfer). + */ + +#include "ivtv-driver.h" +#include "ivtv-cards.h" +#include "ivtv-gpio.h" + +#include <media/ir-kbd-i2c.h> + +/* i2c implementation for cx23415/6 chip, ivtv project. + * Author: Kevin Thayer (nufan_wfk at yahoo.com) + */ +/* i2c stuff */ +#define IVTV_REG_I2C_SETSCL_OFFSET 0x7000 +#define IVTV_REG_I2C_SETSDA_OFFSET 0x7004 +#define IVTV_REG_I2C_GETSCL_OFFSET 0x7008 +#define IVTV_REG_I2C_GETSDA_OFFSET 0x700c + +#ifndef I2C_ADAP_CLASS_TV_ANALOG +#define I2C_ADAP_CLASS_TV_ANALOG I2C_CLASS_TV_ANALOG +#endif /* I2C_ADAP_CLASS_TV_ANALOG */ + +#define IVTV_CS53L32A_I2C_ADDR 0x11 +#define IVTV_CX25840_I2C_ADDR 0x44 +#define IVTV_SAA7115_I2C_ADDR 0x21 +#define IVTV_SAA7127_I2C_ADDR 0x44 +#define IVTV_SAA717x_I2C_ADDR 0x21 +#define IVTV_MSP3400_I2C_ADDR 0x40 +#define IVTV_HAUPPAUGE_I2C_ADDR 0x50 +#define IVTV_WM8739_I2C_ADDR 0x1a +#define IVTV_WM8775_I2C_ADDR 0x1b +#define IVTV_TEA5767_I2C_ADDR 0x60 +#define IVTV_UPD64031A_I2C_ADDR 0x12 +#define IVTV_UPD64083_I2C_ADDR 0x5c +#define IVTV_TDA985X_I2C_ADDR 0x5b + +/* This array should match the IVTV_HW_ defines */ +static const u8 hw_driverids[] = { + I2C_DRIVERID_CX25840, + I2C_DRIVERID_SAA711X, + I2C_DRIVERID_SAA7127, + I2C_DRIVERID_MSP3400, + I2C_DRIVERID_TUNER, + I2C_DRIVERID_WM8775, + I2C_DRIVERID_CS53L32A, + I2C_DRIVERID_TVEEPROM, + I2C_DRIVERID_SAA711X, + I2C_DRIVERID_TVAUDIO, + I2C_DRIVERID_UPD64031A, + I2C_DRIVERID_UPD64083, + I2C_DRIVERID_SAA717X, + I2C_DRIVERID_WM8739, + 0 /* IVTV_HW_GPIO dummy driver ID */ +}; + +/* This array should match the IVTV_HW_ defines */ +static const char * const hw_drivernames[] = { + "cx2584x", + "saa7115", + "saa7127", + "msp3400", + "tuner", + "wm8775", + "cs53l32a", + "tveeprom", + "saa7114", + "tvaudio", + "upd64031a", + "upd64083", + "saa717x", + "wm8739", + "gpio", +}; + +static int attach_inform(struct i2c_client *client) +{ + struct ivtv *itv = (struct ivtv *)i2c_get_adapdata(client->adapter); + int i; + + IVTV_DEBUG_I2C("i2c client attach\n"); + for (i = 0; i < I2C_CLIENTS_MAX; i++) { + if (itv->i2c_clients[i] == NULL) { + itv->i2c_clients[i] = client; + break; + } + } + if (i == I2C_CLIENTS_MAX) { + IVTV_ERR("insufficient room for new I2C client!\n"); + } + return 0; +} + +static int detach_inform(struct i2c_client *client) +{ + int i; + struct ivtv *itv = (struct ivtv *)i2c_get_adapdata(client->adapter); + + IVTV_DEBUG_I2C("i2c client detach\n"); + for (i = 0; i < I2C_CLIENTS_MAX; i++) { + if (itv->i2c_clients[i] == client) { + itv->i2c_clients[i] = NULL; + break; + } + } + IVTV_DEBUG_I2C("i2c detach [client=%s,%s]\n", + client->name, (i < I2C_CLIENTS_MAX) ?
