Subject: [RFC v2 06/14] arm/sdei: add system reset callback
Date: Tue, 5 Nov 2019 17:10:48 +0800 [thread overview]
Message-ID: <20191105091056.9541-7-guoheyi@huawei.com> (raw)
In-Reply-To: <20191105091056.9541-1-guoheyi@huawei.com>
For this is a logical device which is not attached to system bus, we
cannot use DeviceClass->reset interface directly. Instead we register
our own reset callback to reset SDEI services when system resets.
