I2c1 and ds2460 drivers

I2c1 and ds2460 driver Linux 2.6.27 on I2C not 2.6.29 on maturity, can not follow that set to do, such as in the board-smartarm.c to add: 499 // static struct i2c_board_info _ initdata smartarm3250_i2c_ds2460_info [] = {500 // {501 // i2c_board_info ("epc-ds2460", 0x40), 502 //}, 503 //}; 698/* I2C based ds2460 on i2c1 */699 // i2c_register_board_info (0, smartarm3250_i2c_ds2460_info, 700 // array_size (bytes); this does not work. Can only be hard, add I2C device binding directly in I2C DRIVER: Drivers/I2C/busses/i2c-pnx.c656 if (pdev-> id = 1) {// i2c2

657 struct i2c_board_info info = {
658 i2c_board_info ("pcf8563", 0xa3> 1 ),
659 };
660 client = i2c_new_device (i2c_pnx-> adapter, & info );
661
662 if (client = NULL ){
663 printk ("Check pcf8563 failed \ n ");
664}
665}
666
667 if (pdev-> id = 0) {// i2c1

668 struct i2c_board_info info2 = {
669 i2c_board_info ("ds2460", 0x80> 1 ),
670 };
671 client = i2c_new_device (i2c_pnx-> adapter, & info2 );
672
673 if (client = NULL ){
674 printk ("Check ds2460 failed \ n ");
675}
676} note that the name in i2c_board_info must be consistent with that in the ID table of ds2460.c; otherwise, registration fails. In addition, the depressing thing is still behind. When I read the EEPROM, I used the i2c_transfer function, and the result was always reading errors. However, this reading function has no problem on omap3530. The Code is as follows: 25 int read_from_ds2460 (unsigned char * kbuf, int start_addr, int Len)
26 {
27 unsigned char tempbuf [8] = {start_addr };
28 int I;
29 int ret = 0;
30
31 // printk ("### abing in % S % d \ n", _ FUNCTION __, _ line __);

32 # If 0
33 struct i2c_msg msgs [] = {
34 {ds2460_client-> ADDR, 0, 1, tempbuf},/* setup read PTR -- start_addr */
35 {ds2460_client-> ADDR, i2c_m_rd, Len, kbuf},/* read from ds2460 */
36 };
37
38 If (kbuf = NULL ){
39 printk ("a null pointer found! \ N ");
40 return-enosys;
41}
42
43 return i2c_transfer (ds2460_client-> adapter, msgs, 2 );
44 # else
45
46 ret = i2c_master_send (ds2460_client, tempbuf, 1 );
47 If (Ret <0 ){
48 printk ("I2C err: % s, % d send data to I2C bus failed \ n", _ FUNCTION __,__ line __);
49 return ret;
50}
51
52 ret = i2c_master_recv (ds2460_client, kbuf, Len );
53 If (Ret <0 ){
54 printk ("I2C err: % s, % d get I2C bus data failed \ n", _ FUNCTION __,__ line __);
55 return ret;
56}
57
58 return 0;
59 # endif
60} changed to i2c_master_send and i2c_master_recv.
