So, leave only ARM/DT specifc details in Documentation/devicetree/bindings/arm/fw-cfg.txt, and rework the fw_cfg sysfs patch (1/4) to only document sysfs specific details in Documentation/ABI/testing/sysfs-firmware-qemu_fw_cfg ? The fw_cfg "datasheet" does exist in QEMU already, so there is something to point at from either/both of the above.
