Subject: [PATCH v9 4/4] ARM: dts: rockchip: add suspend settings for rk3288-evb-rk808
Date: Tue, 25 Nov 2014 15:32:23 +0800	[thread overview]
Message-ID: <1416900743-29204-5-git-send-email-zyw@rock-chips.com> (raw)
In-Reply-To: <1416900743-29204-1-git-send-email-zyw@rock-chips.com>

Add suspend-voltages and necessary pin-states for suspend on
rk3288-evb-rk808 boards. global_pwroff would be pulled high when
RK3288 entering suspend, this pin is a sleep signal for RK808, so
RK808 could goto sleep mode, and some regulators would be disable.

Signed-off-by: Chris Zhong <zyw@rock-chips.com>

Changes in v9:
- update the subject and description

Changes in v8:
- set vdd_gpu to 1.0v during suspend
- add regulator-on-in-suspend before set suspend voltage

Changes in v7:
- add regulator-state-mem sub node for suspend

Changes in v6: None
Changes in v5: None
Changes in v4: None
Changes in v3: None
Changes in v2: None
