Yes, that's a much better name.

Existing board files do have a Boolean enabled/disabled flag per GPIO,
which is currently always true,  whereas this patch series only implements
"enabled" entries. I thought about it briefly, and didn't think that
explicitly disabling GPIOs that the bootloader had already enabled was
likely to be useful. Do you agree? Possibly not since IIRC you added the
tables that contain that Boolean.

Yup. The next posting will include this.
