Indeed, we don't accept new code we legacy bindings.

I don't understand what extra consumption you are trying to avoid,
because if it is the NAND device itself that is able to save power when
it gets unselected, it's really none of you controller's business.

Perhaps it's the time to focus on the controller support and tune the
code base later in a bid to reduce consumption.
