Hello everyone:
I'm writing a driver for a chip named tvp5150a on at51rm9200 platform.
I tried to understand the architecture of i2c driver for linux,
but there're some points that I couldnt understand.
I think the struct i2c_client_address_data is used to probe
a chip attached to the i2c bus, but I can't see how to set it
properly. I've checked others drivers such as msp3400.c,
ds1307.c, saa5249.c, i2c.h, i2c-dev.h, i2c-core.c, and the documents
for i2c in src/Documentation/i2c, but I didnt find any information
useful.
I guess it may work by simply setting the fields of
i2c_client_address_data with "I2C_CLIENT_END", but I dont kno why it
works!
Can somebody tell me the exact meanning of the fields in
i2c_client_address_data? And how should I set them?
Any reply will be appreciate. Thanks.
regards.
