I don't think this will work for me. I'm running this on a PowerPC system, and we use a device tree to represent the I2C devices on the various I2C buses. My driver does not call i2c_new_device. This is done for me in of_register_i2c_devices(). As soon as my driver calls i2c_add_driver(), my I2C probe function will be called, once for each I2C device defined in the device tree. So I don't think I can update the i2c_board_info structure. > > -- > Ben (ben@xxxxxxxxx, http://www.fluff.org/) > > 'a smiley only costs 4 bytes' > -- > To unsubscribe from this list: send the line "unsubscribe linux-i2c" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- Timur Tabi Linux kernel developer at Freescale -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
