Subject: [PATCH v2 9/9] ARM: mstar: Add reboot support
Date: Tue, 28 Jul 2020 19:03:21 +0900 [thread overview]
Message-ID: <20200728100321.1691745-10-daniel@0x0f.com> (raw)
In-Reply-To: <20200728100321.1691745-1-daniel@0x0f.com>
MStar v7 SoCs support reset by writing a magic value to a register
in the "pmsleep" area.
This adds a node for using the syscon reboot driver to trigger a reset.
