See the cover letter. It works OK in sandbox and I've tested it on rockchip and exynos also. Is there a fixed-point implementation somewhere? I remember Acorn had one years ago [1] but I believe it was written in ARM assembler. Perhaps there is another one somewhere. The floating point is limited to the one driver that uses this header, so it doesn't bleed into the build system, etc. and is not built at all unless that driver is enabled.
