hi, 

I want to wakeup my system from sleep mode (echo mem>/sys/power/state) when press the powerkey which connect to the imx6sl  ONOFF pin.

but it failed.  the chip of imx7d  can achieve this function.

Is imx6sl's ONOFF key didn't has the function wakeup system.   

my software environment: yocto L4.1.15_2.1.0-ga.

hardware envionment mcimx6slevk

modify the imx6sl.dtsi as follow:

snvs: snvs@020cc000 {
compatible = "fsl,sec-v4.0-mon", "syscon", "simple-mfd";
reg = <0x020cc000 0x4000>;

snvs_rtc: snvs-rtc-lp {
compatible = "fsl,sec-v4.0-mon-rtc-lp";
regmap = <&snvs>;
offset = <0x34>;
interrupts = <0 19 IRQ_TYPE_LEVEL_HIGH>,
<0 20 IRQ_TYPE_LEVEL_HIGH>;
};

snvs_pwrkey: snvs-powerkey {
compatible = "fsl,sec-v4.0-pwrkey";
regmap = <&snvs>;
interrupts = <0 4 IRQ_TYPE_LEVEL_HIGH>;
linux,keycode = <116>;
gpio-key,wakeup;
};

snvs_poweroff: snvs-poweroff {
compatible = "syscon-poweroff";
regmap = <&snvs>;
offset = <0x38>;
mask = <0x61>;
status = "disabled";
};
};

thandks & best regards.

Hi yan2

what bsp used in the case, please try with nxp bsps described on

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

try snvs_pwrkey example as in  imx6sx.dtsi

linux-imx.git - i.MX Linux Kernel
