Webb26 okt. 2024 · A GPIO bank is an instance of a hardware IP core on a silicon die, usually exposed to the programmer as a coherent range of I/O addresses. Usually each such bank is exposed in the device tree as an individual gpio-controller node, reflecting the fact that the hardware was synthesized by reusing the same IP block a few times over.
