Use i2c_add_numbered_adapter() to allow platform devices to specify fixed bus numbers when needed.Not sure about this. Doesn't it break the current approach? Please, double check that. -- With Best Regards, Andy Shevchenko
If pdev->id is PLATFORM_DEVID_NONE(-1) then i2c_add_numbered_adapter() falls back to dynamic allocation and calls i2c_add_adapter(). Many existing i2c drivers use the same approach, see i2c-pxa.c and i2c-pnx.c etc.
