Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56. -The driver does not probe any address, so you must force the address. +The driver does not probe any address, so you explicitly instantiate the +devices. Example: -$ modprobe max6875 force=0,0x50 +$ modprobe max6875 +$ echo max6875 0x50 > /sys/bus/i2c/devices/i2c-0/new_device The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple addresses. For example, for address 0x50, it also reserves 0x51. diff --git a/drivers/misc/eeprom/max6875.c b/drivers/misc/eeprom/max6875.c index 3c0c58e..5a6b2bc 100644 --- a/drivers/misc/eeprom/max6875.c +++ b/drivers/misc/eeprom/max6875.c @@ -33,12 +33,6 @@ #include <linux/i2c.h> #include <linux/mutex.h> -/* Do not scan - the MAX6875 access method will write to some EEPROM chips */ -static const unsigned short normal_i2c[] = { I2C_CLIENT_END }; - -/* Insmod parameters */ -I2C_CLIENT_INSMOD_1(max6875); - /* The MAX6875 can only read/write 16 bytes at a time */ #define SLICE_SIZE 16 #define SLICE_BITS 4 @@ -146,31 +140,21 @@ static struct bin_attribute user_eeprom_attr = { .read = max6875_read, }; -/* Return 0 if detection is successful, -ENODEV otherwise */ -static int max6875_detect(struct i2c_client *client, int kind, - struct i2c_board_info *info) +static int max6875_probe(struct i2c_client *client, + const struct i2c_device_id *id) { struct i2c_adapter *adapter = client->adapter; + struct max6875_data *data; + int err; if (!i2c_check_functionality(adapter, I2C_FUNC_SMBUS_WRITE_BYTE_DATA | I2C_FUNC_SMBUS_READ_BYTE)) return -ENODEV; - /* Only check even addresses */ + /* Only bind to even addresses */ if (client->addr & 1) return -ENODEV; - strlcpy(info->type, "max6875", I2C_NAME_SIZE); - - return 0; -} - -static int max6875_probe(struct i2c_client *client, - const struct i2c_device_id *id) -{ - struct max6875_data *data; - int err; - if (!(data = kzalloc(sizeof(struct max6875_data), GFP_KERNEL))) return -ENOMEM; @@ -222,9 +206,6 @@ static struct i2c_driver max6875_driver = { .probe = max6875_probe, .remove = max6875_remove, .id_table = max6875_id, - - .detect = max6875_detect, - .address_data = &addr_data, }; static int __init max6875_init(void) |
