The reason this isn't in device tree at the minute is that suspend to disk and suspend to RAM are somewhat Linux specific concepts and the whole thing gets more and more dynamic as time moves forwards with the suspend state for practical systems depending on the instantaneous device state prior to entering suspend and the bits that are fixed often involving sequencing elements and so on which get fixed in hardware and/or bootloader. Do you have practical systems where this is needed?
It's also not clear to me hat the -disabled properties make sense; if we have properties for the state when enabled I'd expect them to allow things to be marked as enabled or disabled (with don't touch as the default). [unhandled content-type:application/pgp-signature] | |
