| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dwc_460ex SATA driver has become available on non-powerpc architectures and may cause randconfig build errors when CONFIG_DMADEVICES is not set and SATA_DWC_OLD_DMA is enabled: warning: (SATA_DWC_OLD_DMA) selects DW_DMAC_CORE which has unmet direct dependencies (DMADEVICES) ERROR: "dw_dma_probe" [drivers/ata/sata_dwc_460ex.ko] undefined! ERROR: "dw_dma_remove" [drivers/ata/sata_dwc_460ex.ko] undefined! This adds an explcit Kconfig dependency to CONFIG_SATA_DWC so we cannot run into broken configurations. While it would also be possible to build the driver with both CONFIG_DMADEVICES and SATA_DWC_OLD_DMA disabled, that case is not useful because there is no fallback to PIO mode when the DMA engine is not usable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently this driver only works with a DesignWare DMA engine which it registers manually using the second "reg" address range and interrupt number from the DT node. This patch makes the driver instead use the "dmas" property if present, otherwise optionally falling back on the old way so existing device trees can continue to work. With this change, there is no longer any reason to depend on the 460EX machine type so drop that from Kconfig.

* | ata: add AMD Seattle platform driverBrijesh Singh2016-04-131-0/+8
|/ | | | | | | | | | | | | | | | | | AMD Seattle SATA controller mostly conforms to AHCI interface with some special register to control SGPIO interface. In the case of an AHCI controller, the SGPIO feature is ideally implemented using the "Enclosure Management" register of the AHCI controller, but those registeres are not implemented in the Seattle SoC. Instead SoC (Rev B0 onwards) provides a 32-bit SGPIO control register which should be programmed to control the activity, locate and fault LEDs. The driver is based on ahci_platform driver.

| | | | | | | | | | | | | | Currently Freescale QorIQ series SATA is supported by ahci_platform driver. Some SoC specific settings have been put in uboot. So whether SATA works or not heavily depends on uboot. This patch will add a new driver to support QorIQ sata which removes the dependency on any other boot loader. Freescale QorIQ series sata, like ls1021a ls2085a ls1043a, is compatible with serial ATA 3.0 and AHCI 1.3 specification.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds ACPI supports for AHCI platform driver, which uses _CLS method to match the device. The following is an example of ASL structure in DSDT for a SATA controller, which contains _CLS package to be matched by the ahci_platform driver: Device (AHC0) // AHCI Controller { Name(_HID, "AMDI0600") Name (_CCA, 1) Name (_CLS, Package (3) { 0x01, // Base Class: Mass Storage 0x06, // Sub-Class: serial ATA 0x01, // Interface: AHCI }) Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000) Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 } }) } Also, since ATA driver should not require PCI support for ATA_ACPI, this patch removes dependency in the driver/ata/Kconfig.

* sata_dwc_460ex: disable COMPILE_TEST againLinus Torvalds2015-02-111-1/+1
| | | | | | | | | | | | | | | | | Commit 84683a7e081f ("sata_dwc_460ex: enable COMPILE_TEST for the driver") enabled this driver for non-ppc460-ex platforms, but it was then disabled for ARM and ARM64 by commit 2de5a9c004e9 ("sata_dwc_460ex: disable compilation on ARM and ARM64") because it's too noisy and broken. This disabled is entirely, because it's too noisy on x86-64 too, and there's no point in disabling architectures one by one. At a minimum, the code isn't 64-bit clean, and even on 32-bit it is questionable whether it makes sense.

Various embedded platforms are implementing ahci controllers. Some were built atop ahci_platform, others were doing their own things. Hans made some structural changes to libahci and librarized ahci_platform so that ahci platform drivers can share more common code. A couple platform drivers are added on top of that and several are added to replace older drivers which were doing their own things (older ones are scheduled to be removed). - Dan finishes the patchset to make libata PM operations asynchronous. Combined with one patch being routed through scsi, this should speed resume measurably. - Various fixes and cleanups from Bartlomiej and others" * 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (61 commits) ata: fix Marvell SATA driver dependencies ata: fix ARASAN CompactFlash PATA driver dependencies ata: remove superfluous casts ata: sata_highbank: remove superfluous cast ata: fix Calxeda Highbank SATA driver dependencies ata: fix R-Car SATA driver dependencies ARM: davinci: da850: update SATA AHCI support ata: add new-style AHCI platform driver for DaVinci DA850 AHCI controller ata: move library code from ahci_platform.c to libahci_platform.c ata: ahci_platform: fix ahci_platform_data->suspend method handling libata: remove unused ata_sas_port_async_resume() stub libata.h: add stub for ata_sas_port_resume libata: async resume libata, libsas: kill pm_result and related cleanup ata: Fix compiler warning with APM X-Gene host controller driver arm64: Add APM X-Gene SoC AHCI SATA host controller DTS entries ata: Add APM X-Gene SoC AHCI SATA host controller driver Documentation: Add documentation for the APM X-Gene SoC SATA host controller DTS binding arm64: Add APM X-Gene SoC 15Gbps Multi-purpose PHY DTS entries ata: ahci_sunxi: fix code formatting ...

Platform changes needed to make DaVinci DA850 SATA AHCI support fully functional are in the separate "ARM: davinci: da850: update SATA AHCI support" commit. Please note that this driver doesn't have the superfluous clock control code as clock is already handled by the generic AHCI platform library code.

While we're here, simplify the dependencies for the CS5535 driver. The CS5536 was used with the Geode processors, but also on MIPS Loongson/Lemote 2 systems, so let its driver be built for these two architectures only, except for build testing purpose.

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.
