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 "ivtv-i2c.h" +#include <media/drv-intf/cx25840.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 + +#define IVTV_CS53L32A_I2C_ADDR 0x11 +#define IVTV_M52790_I2C_ADDR 0x48 +#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_VP27SMPX_I2C_ADDR 0x5b +#define IVTV_M52790_I2C_ADDR 0x48 +#define IVTV_AVERMEDIA_IR_RX_I2C_ADDR 0x40 +#define IVTV_HAUP_EXT_IR_RX_I2C_ADDR 0x1a +#define IVTV_HAUP_INT_IR_RX_I2C_ADDR 0x18 +#define IVTV_Z8F0811_IR_TX_I2C_ADDR 0x70 +#define IVTV_Z8F0811_IR_RX_I2C_ADDR 0x71 +#define IVTV_ADAPTEC_IR_ADDR 0x6b + +/* This array should match the IVTV_HW_ defines */ +static const u8 hw_addrs[IVTV_HW_MAX_BITS] = { + IVTV_CX25840_I2C_ADDR, + IVTV_SAA7115_I2C_ADDR, + IVTV_SAA7127_I2C_ADDR, + IVTV_MSP3400_I2C_ADDR, + 0, + IVTV_WM8775_I2C_ADDR, + IVTV_CS53L32A_I2C_ADDR, + 0, + IVTV_SAA7115_I2C_ADDR, + IVTV_UPD64031A_I2C_ADDR, + IVTV_UPD64083_I2C_ADDR, + IVTV_SAA717x_I2C_ADDR, + IVTV_WM8739_I2C_ADDR, + IVTV_VP27SMPX_I2C_ADDR, + IVTV_M52790_I2C_ADDR, + 0, /* IVTV_HW_GPIO dummy driver ID */ + IVTV_AVERMEDIA_IR_RX_I2C_ADDR, /* IVTV_HW_I2C_IR_RX_AVER */ + IVTV_HAUP_EXT_IR_RX_I2C_ADDR, /* IVTV_HW_I2C_IR_RX_HAUP_EXT */ + IVTV_HAUP_INT_IR_RX_I2C_ADDR, /* IVTV_HW_I2C_IR_RX_HAUP_INT */ + IVTV_Z8F0811_IR_RX_I2C_ADDR, /* IVTV_HW_Z8F0811_IR_HAUP */ + IVTV_ADAPTEC_IR_ADDR, /* IVTV_HW_I2C_IR_RX_ADAPTEC */ +}; + +/* This array should match the IVTV_HW_ defines */ +static const char * const hw_devicenames[IVTV_HW_MAX_BITS] = { + "cx25840", + "saa7115", + "saa7127_auto", /* saa7127 or saa7129 */ + "msp3400", + "tuner", + "wm8775", + "cs53l32a", + "tveeprom", + "saa7114", + "upd64031a", + "upd64083", + "saa717x", + "wm8739", + "vp27smpx", + "m52790", + "gpio", + "ir_video", /* IVTV_HW_I2C_IR_RX_AVER */ + "ir_video", /* IVTV_HW_I2C_IR_RX_HAUP_EXT */ + "ir_video", /* IVTV_HW_I2C_IR_RX_HAUP_INT */ + "ir_z8f0811_haup", /* IVTV_HW_Z8F0811_IR_HAUP */ + "ir_video", /* IVTV_HW_I2C_IR_RX_ADAPTEC */ +}; + +static int get_key_adaptec(struct IR_i2c *ir, enum rc_proto *protocol, + u32 *scancode, u8 *toggle) +{ + unsigned char keybuf[4]; + + keybuf[0] = 0x00; + i2c_master_send(ir->c, keybuf, 1); + /* poll IR chip */ + if (i2c_master_recv(ir->c, keybuf, sizeof(keybuf)) != sizeof(keybuf)) { + return 0; + } + + /* key pressed ?
