You also need to define what happens if neither X-in-suspend property is set. > + regulator-state-mem { > + regulator-volt = <1000000>; > + regulator-mode = <0x8>; > + regulator-off-in-suspend; > + }; Probably best to remove mode from this.

This patch add regulator suspend state to constraint in dt file. The regulation_ constraints structure already has regulator suspend state field as following. The regulator suspend state control the state of regulator according to PM (Power Management) state. - struct regulator_state state_disk - struct regulator_state state_mem - struct regulator_state state_standby Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> --- Documentation/devicetree/bindings/regulator/regulator.txt | 12 ++++++++++++ 1 file changed, 12 insertions(+)
