Hi,
Thank you for your relpay! I have implemented init, probe and attach function.
But I am having some problems with i2c_probe function. After this function is
called i2c_probe(adap, &addr_data, ds2782_attach) it does not call
ds2782_attach function. This function returns -1 and it never calls
ds2782_attach. So I can not register my i2c device.
Any idea??
Tnx,
Benjamin

Hi,
About the battery gas gauge driver , you can make a character driver
and call the i2c functions which are exported in the MVL kernel. The I2C
protocol also is the same just use the slave address 7Eh and register the i2c
client device and you can call i2c reads and writes using the i2c functions
In the init function
Register the character driver
i2c_add_driver
In probe function
Attach the client using the address 7Eh and the file operations
structure and calling i2c_attach_client
You need to only specify the read and write functions in the file structure
In the read function
Set the msg structure with relevant information and call i2c_transfer
In the write function (only if required)
Same as above
I have worked on the bq27200 chip for DM6446 EVM.
Regards,
Jinu Joy
