Besides making things noticably simpler it results in ~2% decrease in the driver LOC count and also ~2% decrease in the driver binary size (as measured on x86-32). Fix piix_set_piomode() documentation while at it. Signed-off-by:

Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq() so the latter can be also used for host controllers supporting 32-bit PIO operations. It is a completely safe thing to do because if 32-bit PIO is not supported or enabled ata_sff_data_xfer32() will fallback to a standard method. Signed-off-by:

Fixes IDE -> libata regression. There shouldn't be any problems with it as corresponding IDE's host driver (aec62xx) 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").

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:
