From 6f5976c0cc0977b1fd168d6ecbf3fb36cf041524 Mon Sep 17 00:00:00 2001 From: Michael Roth Date: Sat, 18 Oct 2025 12:14:04 +0200 Subject: [PATCH] gpio: pca953x: clarify log messages about auto increment feature The probe messages currently print "using AI" and "using no AI", which can be confusing to users unfamiliar with the datasheet term. Clarify these by spelling out "auto increment", which is the meaning of the AI bit described in the register map. No functional change, only clearer log wording and matching comment update.
