* ata: sata_highbank: remove superfluous castBartlomiej Zolnierkiewicz2014-03-26
| | | | | | | | | | hpriv->plat_data is 'void *' so there is no need to cast it to 'struct ecx_plat_data *'. Cc: Mark Langsdorf <mark.langsdorf@calxeda.com> Cc: Rob Herring <robh@kernel.org> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Tejun Heo <tj@kernel.org>
* libahci: Allow drivers to override start_engineHans de Goede2014-02-22
| | | | | | | | | | | | | | Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which needs a special register to be poked before starting the DMA engine. This register gets reset on an ahci_stop_engine call, so there is no other place then ahci_start_engine where this poking can be done. This commit allows drivers to override ahci_start_engine behavior for use by the Allwinner AHCI driver (and potentially other drivers in the future).

* ata: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-02-13
| | | | | | | | | | | 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.

* sata_highbank: clear whole array in highbank_initialize_phys()Dan Carpenter2013-10-27
| | | | | | | | | | | | | | | | The original code used the wrong parameter to clear tx_atten[]. It passed the number of elements instead of sizeof() the array to memset. The other potential issue was that cphy_base[] wasn't cleared. I'm not sure if that was a real problem or not, but I have cleared it in my patch. Instead of using memset(), this patch uses empty initializers as a cleanup.

| * sata, highbank: send extra clock cycles in SGPIO patternsMark Langsdorf2013-08-14
| | | | | | | | | | | | | | | | | | | | | | | | Some SGPIO PICs don't follow the standard very well and expect a certain number of clock cycles or port frames in each SGPIO pattern. Add two optional parameters in the DTB that can provide the number of extra clock cycles to be sent before and after SGPIO pattern. Read those parameters from the DTB and send the extra clock cycles.

| * sata, highbank: set tx_atten override bitsMark Langsdorf2013-08-14
| | | | | | | | | | | | | | | | | | | | | | | | Some board designs do not drive the SATA transmit lines within the specification. The ECME can provide override settings, on a per board basis, to bring the transmit lines within spec. Read those settings from the DTB and program them in. At the time of submission, no production hardware requires this patch. Signed-off-by: Mark Langsdorf <mark.langsdorf@calxeda.com> Signed-off-by: Tejun Heo <tj@kernel.org>

* | sata, highbank: fix ordering of SGPIO signalsMark Langsdorf2013-08-09
|/ | | | | | | | | | | | | The ACTIVITY and ERROR signals were reversed in the original commit. Fix that so that hard drive activity does not show up on the error light, and attempts to indicate that the hard drive is failing do not show up as hard drive activity. This fixes a fairly serious functional bug in the driver, but failing to apply this patch will not cause any stability issues on the system.

* Merge branch 'libata/for-3.10-fixes' into libata/for-3.11Tejun Heo2013-07-02
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Drivers: ata: remove __dev* attributes.Greg Kroah-Hartman2013-01-03
| | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* ata: add platform driver for Calxeda AHCI controllerMark Langsdorf2012-09-13
Calxeda highbank SATA phy has intermittent problems bringing up a link with Gen3 drives. Retrying the phy hard reset can work-around this issue, but each reset also disables spread spectrum support. The reset function also needs to reprogram the phy to enable spread spectrum support. Create a new driver based on ahci_platform to support the Calxeda Highbank SATA controller.
