Fixes IDE -> libata regression. There shouldn't be any problems with it as corresponding IDE's host driver (pdc202xx_new) has been supporting PCI Power Management since Oct 10 2008 (commit feb22b7f "ide: add proper PCI PM support (v2)") and IDE PM since Jun 14 2003 (patch v2.5.73 "ide: Power Management").

QDI65x0 controllers are fully supported by pata_legacy driver so remove no longer needed pata_qdi driver. Leave PATA_QDI config option for compatibility reasons and teach pata_legacy to preserve the old behavior of pata_qdi driver. Acked-by:

Fixes IDE -> libata regression. IDE's it8213 host driver has been supporting those modes (per official documentation) since the initial driver's merge on Feb 7 2007 (commit 9c6712c0 "ide: add it8213 IDE driver"). Signed-off-by:

The suspend()/resume() methods already get the right 'struct device' to get the driver data from -- there's no need to get to the 'struct platform_device' that contains that 'struct device' just to call dev_get_drvdata()... Acked-by:

Since commit [c58543c8: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by:

This pushes timing and other values into preinitialized read-only data sections rather than being inlined into the code. None of these functions are called more than a handful of times, so reducing code size makes sense. Signed-off-by:

This ports the timing values over from the old IDE driver into the new PATA-based one. The comment was lying when it stated the old driver was not MWDMA capable. Boot tested on actual hardware using 'libata.force=mwdma2'. Signed-off-by:

This mirrors a very old commit (3160d541, "sis5513: add ->udma_filter method for chipset_family >= ATA_133") to the old sis5513 IDE driver that prevents certain setups from working. UDMA6 (ATA/133) is not supported on some chipsets and we need to ensure this mode is not chosen even if a connected drive supports it. Port this old patch forward to the new PATA driver to ensure UDMA5 is the highest mode used if that is what is supported. Kernel bugzilla #41582. Reviewed-by:

This is similar to the existing sis_old_port_base() method. We do this same calculation and logic in multiple places (with one more to come in a future patch), so extracting it into a method makes sense. Reviewed-by:

On imx53 AHCI, soft reset fails with IPMS set when PMP is enabled but SATA HDD/ODD is connected to SATA port, do soft reset again to port 0. So the 'ahci_pmp_retry_srst_ops' is required when imx53 ahci is present. Signed-off-by:

This quirk patch fixes one kind of bug inside some Intel Sandybridge chipsets, see reports from https://bugzilla.kernel.org/show_bug.cgi?id=40592. Many guys also have reported the problem before: https://bugs.launchpad.net/bugs/737388 https://bugs.launchpad.net/bugs/794642 https://bugs.launchpad.net/bugs/782389 ...... With help from Tejun, the problem is found to be caused by 32bit PIO mode, so introduce the quirk patch to disable 32bit PIO on SATA piix for some Sandybridge CPT chipsets. Seth also tested the patch on all five affected chipsets (pci device ID: 0x1c00, 0x1c01, 0x1d00, 0x1e00, 0x1e01), and found the patch does fix the problem.
