Subject: [PATCH 2/2] drivers: psci: Allow PSCI node to be disabled
Date: Tue, 8 Nov 2016 17:55:47 +0000 [thread overview]
Message-ID: <20161108175547.31146-2-lorenzo.pieralisi@arm.com> (raw)
In-Reply-To: <20161108175547.31146-1-lorenzo.pieralisi@arm.com>
From: Thierry Reding <treding@nvidia.com>
Allow disabling PSCI support (mostly for testing purposes) by setting
the status property to "disabled". This makes the node behave in much
the same way as proper device nodes.
