No, it's the standard for correlating devices with portions of a shared register block elsewhere. Your use in the I2C node is merely a hack to deal with Linux wanting to deal with indices rather than pointers, combined with a lack of a decent way to look up a device struct from the device node. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
