Following srwarren's suggestion, I've re-split the mailbox driver I had previously submitted so that it only exposes a single channel and leaves the previous "channel" notion up to a firmware-specific device driver. I'll be submitting the firmware-specific driver in a separate mail thread -- hopefully this code is ready now, while I expect to get feeback on the other driver. This code can also be found at https://github.com/anholt/linux/tree/rpi-mbox-only -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
