Subject: [PATCH 2/2] ide: add proper PCI PM support
Date: Sat, 2 Aug 2008 19:17:04 +0200 [thread overview]
Message-ID: <200808021917.04847.bzolnier@gmail.com> (raw)
* Keep pointer to ->init_chipset method also in
struct ide_host and set it in ide_host_alloc_all().
* Add ide_pci_suspend() and ide_pci_resume() helpers
(default ->suspend and ->resume implementations).
* ->init_chipset can no longer be marked __devinit.
* Add proper PCI PM support to IDE PCI host drivers
(rz1000.c and tc86c001.c are skipped for now since
they need to be converted from using ->init_hwif
to use ->init_chipset instead).
