ata: ahci_platform: Add synopsys ahci controller in DT's compatible list SPEAr13xx series of SoCs contain Synopsys AHCI SATA Controller which shares ahci_platform driver with other controller versions. This patch updates DT compatible list for ahci_platform. It also updates and renames binding documentation to more generic name.

SATA nodes are defined to describe on-chip Serial ATA controllers.
Each SATA controller should have its own node.

Documentation: dt-bindings: reformat and order list of ahci-platform compatibles The ahci-platform.txt Device Tree binding documentation is gaining a growing number of compatible strings, and it will gain one more with the addition of the Marvell Armada 380 AHCI support.

ata: ahci_mvebu: new driver for Marvell Armada 380 AHCI interfaces The Marvell Armada 380 SoC includes two AHCI compatible interfaces. However, like all DMA-capable Marvell interface, they require special handling to configure MBus windows. Therefore, this commit adds a new ahci_mvebu driver, which relies on the libahci_platform.c code recently introduced.

ata: add platform driver for Calxeda AHCI controller 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.

ahci-imx: Port to library-ised ahci_platform This avoids the ugliness of creating a nested platform device from probe. While moving it around anyways, move the mk6q phy init code from probe to imx_sata_enable, as the phy needs to be re-initialized on resume too, otherwise the drive won't be recognized after resume. Tested on a wandboard i.mx6 quad. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org>

ARM: sunxi: Add support for Allwinner SUNXi SoCs sata to ahci_platform This patch adds support for the ahci sata controler found on Allwinner A10 and A20 SoCs to the ahci_platform driver. Orignally written by Olliver Schinagl using the approach of having a platform device which probe method creates a new child platform device which gets driven by ahci_platform.c, as done by ahci_imx.c . Refactored by Hans de Goede to add most of the non sunxi specific functionality to ahci_platform.c and use a platform_data pointer from of_device_id for the sunxi specific bits.
