Subject: [PATCH] arm64: dts: mediatek: mt8173 PSCI-1.0 support
Date: Fri, 28 Aug 2015 10:11:59 +0800 [thread overview]
Message-ID: <1440727919-34719-1-git-send-email-fan.chen@mediatek.com> (raw)
From: Fan Chen <fan.chen@mediatek.com>
This patch adds psci comatible properties to support all mandatory
functions of PSCI-1.0, PSCI-0.2 and PSCI-0.1, and system suspend
can be supported in PSCI-1.0.
Signed-off-by: Fan Chen <fan.chen@mediatek.com>
---
Because PSCI-1.0 patches hadn't landed on mainline, this patch is
based on three patch sets below:
[0] http://www.spinics.net/lists/arm-kernel/msg425793.html
PSCI: system suspend support
[1] git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git
psci/unification
[2] http://www.spinics.net/lists/devicetree/msg82017.html
[PATCH 0/6] drivers: firmware: psci: add basic v1.0 support
Before they are merged in, this patch still works fine with psci-0.2
support in current mainline.
