I tested the power consumption on Xplained demo board yesterday. I found that the board can NOT wakeup by pressing the K1 button after suspend to mem. but standby mode is ok.
How to fix this ?
ps: I enabled the CONFIG_AT91_SLOW_CLOCK define in the kernel .config file.

I haven't had a look at the schematic for the xplained but I've got a custom board with a sama5d31 and I'm using a gpio-keys entry for an ordinary gpio pin in the device tree with the wakeup option and that works to wake it from both standby and mem.
