The bindings are based on Bastian Hecht's proposal (see http://www.spinics.net/lists/arm-kernel/msg228129.html). The approach taken here is more minimalistic: instead of describing all hardware characteristics that vary between the SCI device revisions in DT (such as registers layout), that information is stored in the driver and selected based on the compatible property value. Only SCI revisions used on ARM devices are supported through DT, as DT support for SuperH is nowhere down the line. The first three patches clean up the sh-sci driver. They're not strictly required for OF support but make sense nonetheless. The last two patches add OF parsing to the sh-sci driver and create DT bindings documentation. The patches have been test on a Lager board (r8a7790-based). Support for other SoCs will be added as needed. Note that all current Renesas ARM SoCs seem to be compatible with the generic (H)SCI(F)(AB) devices, but the plan is for their DT bindings to list the SoC-specific version in case incompatibilities are found later.
