From 9eac290915cb719fa3b8fd44ff452261461d08d2 Mon Sep 17 00:00:00 2001 From: Binbin Zhou Date: Tue, 10 Jun 2025 19:59:26 +0800 Subject: [PATCH] gpio: loongson-64bit: Correct Loongson-7A2000 ACPI GPIO access mode According to the description of the Loongson-7A2000 ACPI GPIO register in the manual, its access mode should be BIT_CTRL_MODE, otherwise there maybe some unpredictable behavior.
