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/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_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_TX_I2C_ADDR, /* IVTV_HW_Z8F0811_IR_TX_HAUP */ - IVTV_Z8F0811_IR_RX_I2C_ADDR, /* IVTV_HW_Z8F0811_IR_RX_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[] = { - "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_tx_z8f0811_haup", /* IVTV_HW_Z8F0811_IR_TX_HAUP */ - "ir_rx_z8f0811_haup", /* IVTV_HW_Z8F0811_IR_RX_HAUP */ - "ir_video", /* IVTV_HW_I2C_IR_RX_ADAPTEC */ -}; - -static int get_key_adaptec(struct IR_i2c *ir, u32 *ir_key, u32 *ir_raw) -{ - 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 ?
