From dae9750105cf93ac1e156ef91f4beeb53bd64777 Mon Sep 17 00:00:00 2001 From: Xi Ruoyao Date: Fri, 28 Nov 2025 15:50:32 +0800 Subject: [PATCH] gpio: loongson: Switch 2K2000/3000 GPIO to BYTE_CTRL_MODE The manuals of 2K2000 says both BIT_CTRL_MODE and BYTE_CTRL_MODE are supported but the latter is recommended. Also on 2K3000, per the ACPI DSDT the GPIO controller is compatible with 2K2000, but it fails to operate GPIOs 62 and 63 (and maybe others) using BIT_CTRL_MODE. Using BYTE_CTRL_MODE also makes those 2K3000 GPIOs work.
