    arm64: dts: hikey: name the GPIO lines · bbaf867e
    Linus Walleij authored
    This names the GPIO lines on the HiKey board in accordance with
    the 96Board Specification for especially the Low Speed External
    Connector: "GPIO-A" thru "GPIO-L".
    This will make these line names reflect through to userspace
    so that they can easily be identified and used with the new
    character device ABI.
    Some care has been taken to name all lines, not just those used
    by the external connectors, also lines that are muxed into some
    other function than GPIO: these are named "[FOO]" so that users
    can see with lsgpio what all lines are used for.
