The following patchset adds support for the J-core J2, an open-source VHDL reimplementation of the SH-2 ISA, and drivers for the associated SoC devices (interrupt controller, clocksource, and SPI). As arch/sh co-maintainer my intent is to include as much as possible in my pull request for the linux-sh tree. If there are parts outside of arch/sh that can be included in this, please let me know. I'm not clear yet on what the right path to upstream is for the clocksource and irq drivers that are currently only useful/interesting for one arch, or for the DT binding patches. Even if some drivers are delayed going upstream, I would really like to get DT bindings acked and ideally merged, because we want to go ahead with moving the DTB into J2 boot rom where it belongs, and that should only happen with stable bindings.
