Non-static Configurations ^^^^^^^^^^^^^^^^^^^^^^^^^ -Developer boards often play by different rules than product boards, and one -example is the potential need to hotplug SPI devices and/or controllers. - -For those cases you might need to use spi_busnum_to_master() to look -up the spi bus master, and will likely need spi_new_device() to provide the -board info based on the board that was hotplugged. Of course, you'd later -call at least spi_unregister_device() when that board is removed. - When Linux includes support for MMC/SD/SDIO/DataFlash cards through SPI, those configurations will also be dynamic. Fortunately, such devices all support basic device identification probes, so they should hotplug normally. |
