Subject: [PATCH 1/3] Hisilicon/D0x: Set ACPI GTDT always-on flag
Date: Wed, 7 Mar 2018 14:55:45 +0800 [thread overview]
Message-ID: <1520405747-11023-1-git-send-email-heyi.guo@linaro.org> (raw)
From: Jason Zhang <zhangjinsong2@huawei.com>
Timer is always working on Hisilicon D0x, even system enters WFI/WFE,
and there is no other low power status, so we set "always-on" flag in
ACPI GTDT.
