Subject: [PATCH 1/2] arm64: dts: r8a7795: Upgrade to PSCI v1.0 to support Suspend-to-RAM
Date: Fri, 17 Feb 2017 18:00:31 +0100 [thread overview]
Message-ID: <1487350832-29820-2-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1487350832-29820-1-git-send-email-geert+renesas@glider.be>
From: Khiem Nguyen <khiem.nguyen.xt@renesas.com>
>From PSCI v1.0, Suspend-to-RAM is supported via SYSTEM_SUSPEND PSCI
function call. Hence, upgrade PSCI version for R-Car H3 to support
Suspend-to-RAM.
The Suspend-to-RAM is highly dependent on ARM Trusted Firwmare support
since necessary callback functions will be registered after a query
to ARM Trusted Firmware about SYSTEM_SUSPEND support.
Since PSCI v1.0 is backward compatible with PSCI v0.2, CPU Hotplug and
CPUIdle should be able to work normally with this change.
