34/************** Registration interface for I2C client drivers **************/

36/* Since there's no way to auto-probe the I2C devices connected to the I2C
37 * bus on the go7007, we have this silly little registration system that
38 * client drivers can use to register their I2C driver ID and their
39 * detect_client function (the one that's normally passed to i2c_probe).
40 *
41 * When a new go7007 device is connected, we can look up in a board info
42 * table by the USB or PCI vendor/product/revision ID to determine
43 * which I2C client module to load. The client driver module will register
44 * itself here, and then we can call the registered detect_client function
45 * to force-load a new client at the address listed in the board info table.
46 *
47 * Really the I2C subsystem should have a way to force-load I2C client
48 * drivers when we have a priori knowledge of what's on the bus, especially
49 * since the existing I2C auto-probe mechanism is so hokey, but we'll use
50 * our own mechanism for the time being. */
