The use of an IRQ domain ensures that any device tree node interrupts properties are correctly parsed. Describe interrupt-related properties in the device tree binding docs, and the contents of "child" node interrupts property. Update tegra*.dtsi to specify the required interrupt-related properties. Finally, remove the definition of TEGRA_GPIO_TO_IRQ; this macro no longer gives correct results since the IRQ numbers for GPIOs are dynamically allocated.

This patch removes the single vdev limitation of the remoteproc framework so multi-vdev firmwares can be leveraged: VDEV resource entries are parsed when the rproc is registered, and as a result their vrings are set up and the virtio devices are registered (and they go away when the rproc goes away). Moreover, we no longer only support VIRTIO_ID_RPMSG vdevs; any virtio device type goes now. As a result, there's no more any rpmsg-specific APIs or code in remoteproc: it all becomes generic virtio handling.

This approach got us this far, but it has a few drawbacks: 1. Different resource entries end up overloading the same members of 'struct fw_resource' with different meanings. The resulting code is error prone and hard to read and maintain. 2. It's impossible to extend 'struct fw_resource' without breaking the existing firmware images (and we already want to: we can't introduce the new virito device resource entry with the current scheme). 3. It doesn't scale: 'struct fw_resource' must be as big as the largest resource entry type. As a result, smaller resource entries end up utilizing only small part of it. This is fixed by defining a dedicated structure for every resource type, and then converting the resource table to a list of type-value members. Instead of a rigid array of homogeneous structs, the resource table is turned into a collection of heterogeneous structures. This way: 1. Resource entries consume exactly the amount of bytes they need. 2. It's easy to extend: just create a new resource entry structure, and assign it a new type. 3. The code is easier to read and maintain: the structures' members names are meaningful. While we're at it, this patch has several other resource table changes: 1. The resource table gains a simple header which contains the number of entries in the table and their offsets within the table. This makes the parsing code simpler and easier to read. 2. A version member is added to the resource table. Should we change the format again, we'll bump up this version to prevent breakage with existing firmware images. 3. The VRING and VIRTIO_DEV resource entries are combined to a single VDEV entry. This paves the way to supporting multiple VDEV entries. 4. Since we don't really support 64-bit rprocs yet, convert two stray u64 members to u32.

Every pair of AMP processors share two vrings, which are used to send and receive the messages over shared memory. The header of every message sent on the rpmsg bus contains src and dst addresses, which make it possible to multiplex several rpmsg channels on the same vring. Every rpmsg channel is a device on this bus. When a channel is added, and an appropriate rpmsg driver is found and probed, it is also assigned a local rpmsg address, which is then bound to the driver's callback. When inbound messages carry the local address of a bound driver, its callback is invoked by the bus. This patch provides a kernel interface only; user space interfaces will be later exposed by kernel users of this rpmsg bus. Designed with Brian Swetland <swetland@google.com>.

This is counter-intuitive and awkward at the very least because, when setting the scrub rate, userspace has to write to sysfs and then read it back to check error status of the operation. As Tony notes, best it would be to not have the sdram_scrub_rate in sysfs if scrub rate support is not implemented. It is too late about that and a bunch of drivers on a bunch of arches would need to be changed and tested which is not a trivial task ATM. Instead, settle for the next best thing of returning -ENODEV when implementation is missing and -EINVAL when there was an error encountered while setting the scrub rate.
