By reconfiguring few GPIOs in the dts file we can make duovero parlor hit retention during idle: 1. Let's a larger debounce value for gpio-keys This will then make gpio-keys use software debounce and the GPIO debounce clock is not enabled. 2. Let's allow WLAN suspend for mwifiex This can be done just by adding keep-power-in-suspend. 3. Let's reconfigure smsc911x driver to use GPIO edge interrupt This will allow using NFSroot while the system idles, and the kernel has quite a few dts files with "smsc,lan9115" compatible using edge interrupts. Then to have the system hit core retention during idle, the UARTs needs to be idled and USB modules need to be unloaded or unbound.
