Thanks, I will fix.

# ls Documentation/devicetree/bindings/ata/
ahci-platform.txt         exynos-sata.txt           pata-arasan.txt

By comparison with the other files in the directory, no. Using _ instead
of - is slightly unorthodox but not unknown within the
devicetree/bindings subdirectories.

Yes.
