Subject: Add PSCI support
Date: Tue, 7 Feb 2017 09:43:23 +0100 [thread overview]
Message-ID: <20170207084327.7691-1-s.hauer@pengutronix.de> (raw)
This series implements the ARM "Power State Coordination Interface"
(PSCI). This is needed to enable SMP on some SoCs like the i.MX7 with
a mainline Kernel. Currently only the bare minimum is supported, just
enough to enable and disable the secondary CPU.
