It will try to match all device nodes under probed buses to an of_platform device. > The DTS file spi entry look similar to the i2c entries. > Those are treated as 'platform' devices. There is glue code in arch/powerpc/sysdev/fsl_soc.c:of_fsl_spi_probe() to create platform devices from the device nodes. It doesn't seem to be registered as an initcall, though -- you need to call it from platform code. See mpc832x_rdb.c for an example. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
