Has TI gotten gpio wake up working yet?
I setup MCU_GPIO0_0 as a wake up pin and re-enabled the cbass_mcu node in the lpmdemo device tree. However when I try to sleep, gpio-keys fails to setup the gpio as a wakeup source...
gpio-keys {
compatible = "gpio-keys";
power {
label = "Wake";
gpios = <&mcu_gpio0 0 GPIO_ACTIVE_HIGH>;
linux,code = <KEY_WAKEUP>;
debounce-interval = <20>;
wakeup-source;
};
};
&cbass_mcu {
status = "okay";
};

Also is it possible to use the EXTINTn pin to wake up the SOC?
