From 0674188f2f4d38d74aa863f17373d76256f2ed09 Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Tue, 17 Dec 2024 15:37:04 +0800 Subject: [PATCH] ACPI: EC: Enable EC support on LoongArch by default Commit a6021aa24f6417416d933 ("ACPI: EC: make EC support compile-time conditional") only enable ACPI_EC on X86 by default, but the embedded controller is also widely used on LoongArch laptops so we also enable ACPI_EC for LoongArch. The laptop driver cannot work without EC, so also update the dependency of LOONGSON_LAPTOP to let it depend on APCI_EC.
