ata: libata-eh: Simplify reset operation management

2025-07-16T07:31:43+00:00

Introduce struct ata_reset_operations to aggregate in a single structure the definitions of the 4 reset methods (prereset, softreset, hardreset and postreset) for a port. This new structure is used in struct ata_port to define the reset methods for a regular port (reset field) and for a port-multiplier port (pmp_reset field). A pointer to either of these fields replaces the 4 reset method arguments passed to ata_eh_recover() and ata_eh_reset(). The definition of the reset methods for all drivers is changed to use the reset and pmp_reset fields in struct ata_port_operations. A large number of files is modifed, but no functional changes are introduced. Suggested-by: Niklas Cassel Signed-off-by: Damien Le Moal Reviewed-by: Niklas Cassel Reviewed-by: Martin K.

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

2014-05-10T02:37:49+00:00

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable. Benefits of this change: * unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n and CONFIG_PM_RUNTIME=y configurations * easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in the future * more consistent code (there are host drivers which are using the correct CONFIG_PM_SLEEP checks already) The patch leaves the core libata code and ->port_[suspend,resume] support in sata_[inic162x,nv,sil24].c alone for now.

ata: delete non-required instances of include

2014-02-13T21:40:56+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

Separate out ata_bmdma_qc_issue() from ata_sff_qc_issue() such that ata_sff_qc_issue() only deals with non-BMDMA SFF protocols (PIO and nodata) while ata_bmdma_qc_issue() deals with the BMDMA protocols and uses ata_sff_qc_issue() for non-DMA commands.
