i went looking for examples of that property in the current linux
kernel code base, and was a bit puzzled to see that *all* references
to that property -- both the setting and the processing -- is for
powerpc exclusively. searching from the very top of the kernel source:
$ grep -rl virtual-reg *
arch/powerpc/boot/dts/wii.dts
arch/powerpc/boot/dts/rainier.dts
arch/powerpc/boot/dts/sequoia.dts
arch/powerpc/boot/dts/ep405.dts
arch/powerpc/boot/dts/glacier.dts
arch/powerpc/boot/dts/bluestone.dts
arch/powerpc/boot/dts/redwood.dts
arch/powerpc/boot/dts/icon.dts
arch/powerpc/boot/dts/fsp2.dts
arch/powerpc/boot/dts/bamboo.dts
arch/powerpc/boot/dts/haleakala.dts
arch/powerpc/boot/dts/kilauea.dts
arch/powerpc/boot/dts/taishan.dts
arch/powerpc/boot/dts/eiger.dts
arch/powerpc/boot/dts/canyonlands.dts
arch/powerpc/boot/dts/katmai.dts
arch/powerpc/boot/dts/holly.dts
arch/powerpc/boot/dts/ebony.dts
arch/powerpc/boot/dts/makalu.dts
arch/powerpc/boot/dts/iss4xx.dts
arch/powerpc/boot/dts/obs600.dts
arch/powerpc/boot/dts/sam440ep.dts
arch/powerpc/boot/dts/arches.dts
arch/powerpc/boot/dts/akebono.dts
arch/powerpc/boot/dts/gamecube.dts
arch/powerpc/boot/dts/iss4xx-mpic.dts
arch/powerpc/boot/dts/walnut.dts
arch/powerpc/boot/dts/yosemite.dts
arch/powerpc/boot/dts/acadia.dts
arch/powerpc/boot/dts/warp.dts
arch/powerpc/boot/dts/currituck.dts
arch/powerpc/boot/dts/hotfoot.dts
arch/powerpc/boot/treeboot-walnut.c
arch/powerpc/boot/ebony.c
arch/powerpc/boot/ugecon.c
arch/powerpc/boot/devtree.c
arch/powerpc/boot/uartlite.c
$
so if the device tree processing code under drivers/of doesn't even
recognize that property, how is it officially part of the spec? or am
i misreading something?
