2015-06-03ahci: Store irq number in struct ahci_host_privRobert Richter
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 Lambert
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 Gordeev
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 Ténart
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 Zolnierkiewicz
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 Gortmaker
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 Heo
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 Han
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>
