SPI device driver question

[Jerry Shao]

Thanks.

Should I have to rebuild kernel when a new spi slave device is added? 

Is any non-static way (no need to rebuild kernel) to register spi slave device in driver level?  That case I don't have to rebuild kernel, but using driver modules to fill necessary devive info and register driver.

Yes, exactly. As with platform_devices, the .name field needs to match
that of the driver.  Note that the probe function is not invoked
immediately when spi_register_driver is called.  It will be called
later in the boot sequence.
