2016-02-09devicetree: update documentation for fw_cfg ARM bindingsGabriel Somlo1-36/+2
Remove fw_cfg hardware interface details from Documentation/devicetree/bindings/arm/fw-cfg.txt, and replace them with a pointer to the authoritative documentation in the QEMU source tree.

2015-01-13devicetree: document ARM bindings for QEMU's Firmware Config interfaceLaszlo Ersek1-0/+72
Peter Maydell suggested that we describe new devices / DTB nodes in the kernel Documentation tree that we expose to arm "virt" guests in QEMU. Although the kernel is not required to access the fw_cfg interface, "Documentation/devicetree/bindings/arm" is probably the best central spot to keep the fw_cfg description in.
