From mboxrd@z Thu Jan 1 00:00:00 1970 From: zyw@rock-chips.com (Chris Zhong) Date: Fri, 7 Nov 2014 21:49:36 +0800 Subject: [PATCH v7 4/5] ARM: dts: add RK3288 suspend support In-Reply-To: <1415368177-6637-1-git-send-email-zyw@rock-chips.com> References: <1415368177-6637-1-git-send-email-zyw@rock-chips.com> Message-ID: <1415368177-6637-5-git-send-email-zyw@rock-chips.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
