2018-05-11libata: convert core and drivers to ->hw_tag usageJens Axboe1-2/+2
Anything that goes to the hardware should use ->hw_tag, anything related to internal lookup should be using ->tag. Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Tejun Heo <tj@kernel.org>
2017-05-16ata: update references for libata documentationMauro Carvalho Chehab1-1/+1
The libata documentation is now using ReST. Update references to it to point to the new place. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2015-06-03ahci: Store irq number in struct ahci_host_privRobert Richter1-1/+3
Currently, ahci supports only msi and intx. To also support msix the handling of the irq number need to be changed. The irq number for msix devices is taken from msi_list instead of pci_dev. Thus, the irq number of a device needs to be stored in struct ahci_host_priv now. This allows the host controller to be activated in a generic way. This change is only intended for ahci drivers. For that reason the irq number is stored in struct ahci_host_priv used only by ahci drivers. Thus, the ABI changes only for ahci_host_activate(), but existing ata drivers (about 50) are unaffected and keep unchanged. All users of ahci_host_activate() have been updated. While touching drivers/ata/libahci.c, doing a small code cleanup in ahci_port_start(). Signed-off-by: Robert Richter <rrichter@cavium.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2015-04-08ata: remove deprecated use of pci apiQuentin Lambert1-5/+5
Replace occurences of the pci api by appropriate call to the dma api. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr) @deprecated@ idexpression id; position p; @@ ( pci_dma_supported@p ( id, ...) | pci_alloc_consistent@p ( id, ...) ) @bad1@ idexpression id; position deprecated.p; @@ ...when != &id->dev when != pci_get_drvdata ( id ) when != pci_enable_device ( id ) ( pci_dma_supported@p ( id, ...) | pci_alloc_consistent@p ( id, ...) ) @depends on !bad1@ idexpression id; expression direction; position deprecated.p; @@ ( - pci_dma_supported@p ( id, + dma_supported ( &id->dev, ... + , GFP_ATOMIC ) | - pci_alloc_consistent@p ( id, + dma_alloc_coherent ( &id->dev, ... + , GFP_ATOMIC ) ) Signed-off-by: Quentin Lambert <lambert.quentin@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2014-10-06AHCI: Move host activation code into ahci_host_activate()Alexander Gordeev1-2/+1
Currently host activation done by calling either function ahci_host_activate() or ata_host_activate(). Consolidate the code by only calling ahci_host_activate() for all AHCI devices.

2014-07-30ata: libahci_platform: move port_map parameters into the AHCI structureAntoine Ténart1-1/+1
This patch moves force_port_map and mask_port_map into the ahci_host_priv structure. This allows to modify them into the AHCI framework. This is needed by the new dt bindings representing ports as the port_map mask is computed automatically. Parameters modifying force_port_map, mask_port_map and flags have been removed from the ahci_platform_init_host() function, and inputs in the ahci_host_priv structure are now directly filed.

2014-05-09ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host driversBartlomiej Zolnierkiewicz1-3/+3
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.

2014-02-13ata: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-07-02Merge branch 'libata/for-3.10-fixes' into libata/for-3.11Tejun Heo1-1/+1
libata/for-3.10-fixes never got submitted during v3.10 cycle. Merge it into for-3.11 so that it can be routed together with other changes scheduled for v3.11. Three trivial conflicts in drivers/ata/sata_rcar.c. All are caused by 1b20f6a9ad ("sata_rcar: add 'base' local variable to some functions") conflicting with logic updates in for-3.10-fixes. The offending commit simply adds local variable @base on functions which dereferences sata_rcar_priv->base multiple times. The resolutions are trivial - applying s/priv->base/base/ in the conflicting logic updates. Signed-off-by: Tejun Heo <tj@kernel.org>
2013-06-02ata: use pci_get_drvdata()Jingoo Han1-2/+2
Use the wrapper function for getting the driver data using pci_dev instead of using dev_get_drvdata() with &pdev->dev, so we can directly pass a struct pci_dev. This is a purely cosmetic change. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Tejun Heo <tj@kernel.org>
