It's up to the board manufacturer to decide whether their product has power management and support for sleep/suspend and related features like waking on USB activity. However this costs $€£ so 99.999% of manufacturers believe their product is power efficient and can be left on permanently so they do not include it. I doubt Rockchip manufacturers will be different from Amlogic et. al.
Wake from IR is normally possible with customised uboot. Our challenge will be providing support with Generic uboot, so no guarantees.
