From 8a58cd577f019dee00bdb0ffa52e38aab44154e4 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Sat, 7 Oct 2023 20:55:50 +0800 Subject: [PATCH] gpio: vf610: update comment for i.MX8ULP and i.MX93 legacy compatibles i.MX8ULP and i.MX93 legacy compatible strings use dual regs, while new compatible strings use one reg. The "support old compatible strings" is not clear to reflect the fact, so update it.
