Hello, I'm currently working on a driver for an I2C device (which is a bridge to SPI, just FYI) using the "new" driver model with probe/remove. My used uClinux version is 20080808. As this is done on a board (Coldfire 5208) with a fixed configuration I added a new I2C_BOARD_INFO to my i2c_board_info. But after loading the driver module for the new device, my probe function doesn't get called. After some investigations I found out that the I2C bus num doesn't match the preconfigured one during driver-device comparison, so my statically declared list of devices is useless. I check other I2C bus implementations and found that their bus numbers are configured in a platform device. But the I2C Bus driver for Coldfires doesn't support this. I work around my problem by setting the adapter number to 0 and call i2c_add_numbered_adapter instead. Now i figured other things: * I must not specify the pcf8563 rtc and tmp101 in the i2c_board_info. Otherweise they weren't detected. They seem to use the old driver model. Is this behavior as expected? * Other I2C bus drivers are using platform devices for specifying the bus number. But in the meanwhile compared to 20090520 e.g. i2c-mpc does not support the bus number any more. Is this intended? How can I declare a static list of I2C devices then?
Hopefully someone can answer/comment this questions/problems.
