* The config option for ahci_st driver was renamed from CONFIG_SATA_AHCI_ST to CONFIG_AHCI_ST but Makefile was not updated. Fix it (also while at it move the ahci_st driver entry below ahci_imx and ahci_sunxi ones). * Fix a few build issues in the ahci_st driver itself. Signed-off-by:

As far as I know, the CS5520 and CS5530 chipsets were only used with 32-bit x86 Geode processors, so I think their drivers are only needed on this architecture, except for build testing purpose. 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.

Prompted by the social effort in the US to discourage usage of the adjective "retarded". In this case we needlessly anthropomorphize hard drives. The implication is that due to design deficiencies in the device reset recovery time is negatively impacted. We can simply clearly state that fact. "Exceptional devices cause outliers in reset recovery time." This steers clear of any unintended comparison of such devices to humans with cognitive disabilities. Signed-off-by:

Since the 3.13 release the ahci_imx driver has proper devicetree enabled support for ahci on imx53 and that is used instead of the old board file created imx53-ahci platform device. Note this patch also complete drops the id-table, an id-table is not needed for a single id platform driver, the name field in the driver struct suffices. And the code already has an explicit "MODULE_ALIAS("platform:ahci");" so the id-table is not needed for that either. Cc: Marek Vasut <marex@denx.de> Signed-off-by: -

On OMAP platforms the device needs to be runtime resumed before it can be accessed. The OMAP HWMOD framework takes care of enabling the module and its resources based on the device's runtime PM state. In this patch we runtime resume during .probe() and runtime suspend after .remove(). We also update the runtime PM state during .resume(). CC: Balaji T K <balajitk@ti.com> Signed-off-by:

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:

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. Signed-off-by:

ahci_probe consists of 3 steps: 1) Get resources (get mmio, clks, regulator) 2) Enable resources, handled by ahci_platform_enable_resouces 3) The more or less standard ahci-host controller init sequence This commit refactors step 1 and 3 into separate functions, so the platform drivers for AHCI implementations which need a specific order in step 2, and / or need to do some custom register poking at some time, can re-use ahci-platform.c code without needing to copy and paste it. Note that ahci_platform_init_host's prototype takes the 3 non function members of ahci_platform_data as arguments, the idea is that drivers using the new exported utility functions will not use ahci_platform_data at all, and hopefully in the future ahci_platform_data can go away entirely. tj: Minor comment formatting updates.

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). Signed-off-by:

Using devm_ioremap_resource() can lead to code simplication, as we don't need to explicitily check for error returned by platform_get_resource(). Also, no need to print an error message when devm_ioremap_resource() fails, as the OOM code code will shout loudly on such condition. Signed-off-by:
