Subject: [RFC][PATCH 0/4] ahci controller runtime PM support

Hi all,

The ata port runtime PM support patches have been merged.
Now I move on to ahci controller runtime PM support.

My test enviroment is:
1. use nfsroot, so disk is not mounted. AHCI controller can be runtime suspended.
2. use eSATA to test if hot plug works with port/controller runtime suspended.

I send these RFC patches to get feedbacks.
Any comment is much appriciated.

[RFC][PATCH 1/4] ahci: port legacy pm interface to struct dev_pm_ops
[RFC][PATCH 2/4] ahci: add runtime PM callbacks
[RFC][PATCH 3/4] ata: runtime suspend port if no device attached
[RFC][PATCH 4/4] ahci: support hot plug when port/controller is runtime suspended

Thanks,
Lin Ming
