An additional request inline.  Doesn't effect this patch 'as such'.

Also the file name thing just below here.

File naming should match the compatible.

ashahi-kasei,ak8975.yaml

Nothing to do with your patch obviously but this is horrible...
+ the driver will quite happily take an interrupt instead.

Do you mind documenting the interrupt here as well?

Should be a separate patch though.  So a follow up one to
this one.  The 
arch/arm/boot/dts/motorola-mapphone-common.dtsi
does it that way, unlike the samsung s3 which uses the gpio
binding (I think it's the only one against quite a few
using interrupts).

Also switch the example to an interrupts one so we don't
encourage anyone to go the gpios route.

Note can be a follow up if this series is otherwise ready to go.
