From: Ozan Durgut <[email protected]> The current naming convention for GPIO expanders across ADI SC5xx device trees is inconsistent. This patch updates the node names to correct indexing and clarify hardware location.
For SC573, SC584, and SC589 evaluation SBCs, switch to zero-based indexing to align with standard conventions. For SC594 and SC598 SoM + carrier evaluation kits, rename the nodes to crr_gpio_expander. This prefix indicates which board the expander is on.
