Support for partial array self refresh

Hello,
I was studying mobile power management and got feature in mobile ram called 'Partial Array Self Refresh'(PASR)
I am searching for a mobile phone having linux OS supporting this feature but have not got a one.

Can anyone please tell me that is this feature is supported in current linux mobile phones or if not, how can we do this?

Based on my guess, I think this feature is hardware dependent. The refreshing circuit has to be built-in in the phone or whatever device that support this type of DRAM.

Still not sure, but I found a good description on PASR from the ACPI website (lesswatts.org):

It seemed it is programmable.....sorry.....cannot say much.
