2007-07-10pata_mpc52xx: suspend/resume supportDomen Puncer1-2/+16
Implement suspend and resume routines for mpc52xx ata driver. Tested on Lite5200b with deep-sleep and low-power (not yet in-tree) modes. Signed-off-by: Domen Puncer <domen.puncer@telargo.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-05-11libata: reimplement suspend/resume support using sdev->manage_start_stopTejun Heo1-4/+0
Reimplement suspend/resume support using sdev->manage_start_stop. * Device suspend/resume is now SCSI layer's responsibility and the code is simplified a lot. * DPM is dropped. This also simplifies code a lot. Suspend/resume status is port-wide now. * ata_scsi_device_suspend/resume() and ata_dev_ready() removed. * Resume now has to wait for disk to spin up before proceeding. I couldn't find easy way out as libata is in EH waiting for the disk to be ready and sd is waiting for EH to complete to issue START_STOP. * sdev->manage_start_stop is set to 1 in ata_scsi_slave_config(). This fixes spindown on shutdown and suspend-to-disk. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-28libata: convert the remaining PATA drivers to new init modelTejun Heo1-25/+21
Convert pdc_adma, pata_cs5520, pata_isapnp, pata_ixp4xx_cf, pata_legacy, pata_mpc52xx, pata_mpiix, pata_pcmcia, pata_pdc2027x, pata_platform, pata_qdi, pata_scc and pata_winbond to new init model. * init_one()'s now follow more consistent init order * cs5520 now registers one host with two ports, not two hosts. If any of the two ports are disabled, it's made dummy as other drivers do. Tested pdc_adma and pata_legacy. Both are as broken as before. The rest are compile tested only.

Some LLDs were missing scsi device PM callbacks while having host/port suspend support. Add missing ones. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-02-09libata: add another IRQ calls (libata drivers)Akira Iguchi1-0/+2
This patch is against each libata driver. Two IRQ calls are added in ata_port_operations. - irq_on() is used to enable interrupts. - irq_ack() is used to acknowledge a device interrupt. In most drivers, ata_irq_on() and ata_irq_ack() are used for irq_on and irq_ack respectively. In some drivers (ex: ahci, sata_sil24) which cannot use them as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

2007-02-09libata: convert to iomapTejun Heo1-14/+14
Convert libata core layer and LLDs to use iomap. * managed iomap is used. Pointer to pcim_iomap_table() is cached at host->iomap and used through out LLDs. This basically replaces host->mmio_base. * if possible, pcim_iomap_regions() is used Most iomap operation conversions are taken from Jeff Garzik <jgarzik@pobox.com>'s iomap branch.

2007-02-09libata: update libata LLDs to use devresTejun Heo1-38/+11
Update libata LLDs to use devres. Core layer is already converted to support managed LLDs. This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.
