SubjectRe: [PATCH 1/2] gpio: add pin biasing and drive mode to gpiolib
> gpiolib handles input and output, high and low because that's all that could reasonably be expected to a) always work and b) be changed at run time in the driver.

Also your comment re simply in or out on or off is incorrect. Pins may
also be in use by firmware and the like and in a 'neither' state.
Something certain gpio people seem to be in denial over.
