Subject: [PATCH v8 3/4] ARM: dts: add RK3288 suspend support
Date: Sat, 15 Nov 2014 19:45:09 +0800 [thread overview]
Message-ID: <1416051910-16730-4-git-send-email-zyw@rock-chips.com> (raw)
In-Reply-To: <1416051910-16730-1-git-send-email-zyw@rock-chips.com>
add pmu sram node for suspend, add global_pwroff pinctrl.
The pmu sram is used to store the resume code.
global_pwroff is held low level at work, it would be pull to high
when entering suspend. reference this in the board DTS file since
some boards need it.
ddrio_pwroff is power switch of ddr_controller, if you want to cut off
power rail of ddr_controller during suspend, please reference it.
ddr0_retention/ddr1_retention are the retention mode switches, if you
want to use the retention mode during suspend, please reference them.
