This commit adds suspend/resume support to the ahci_mvebu driver. The suspend hook doesn't do anything special despite calling the generic ahci_platform_suspend_host() function. However, the resume hook has to restore the MBus windows configuration, as well as the regret option. Tested on Marvell Armada 388 GP.

It turned out the irq vector of the msix can be obtained from struct msix_entry. This makes the lookup function for msi_desc obsolete. This fixes a build error if PCI_MSI is unset: drivers/ata/ahci.c: In function ‘msix_get_desc’: drivers/ata/ahci.c:1210:2: error: ‘struct pci_dev’ has no member named ‘msi_list’ Catched by Fengguang's build bot.

This patch adds support for Cavium's ThunderX host controller. The controller resides on the SoC and is a AHCI compatible SATA controller with one port, compliant with Serial ATA 3.1 and AHCI Revision 1.31. There can exists multiple SATA controllers on the SoC. The controller depends on MSI-X support since the PCI ECAM controller on the SoC does not implement MSI nor lagacy intx interrupt support. Thus, during device initialization, if MSI fails MSI-X will be used to enable the device's interrupts. The controller uses non-standard BAR0 for its register range. The already existing device lookup (vendor and device id) that is already implemented for other host controllers is used to change the PCI BAR.

This patch adds generic MSI-X support for single interrupts to the SATA PCI driver. MSI-X support is needed for host controller that only have MSI-X support implemented, but no MSI or intx. This patch only adds support for single interrupts, multiple per-port MSI-X interrupts are not yet implemented. The new implementation still initializes MSIs first. Only if that fails, the code tries to enable MSI-X. If that fails too, setup is continued with intx interrupts. To not break other chips by this generic code change, there are the following precautions: * Interrupt ranges are not enabled at all. * Only single interrupt mode is enabled for msix cap devices. Thus, only one interrupt will be setup. * During the discussion with Tejun we agreed to change the init sequence from msix-msi-intx to msi-msix-intx. Thus, if a device offers msi and init does not fail, the msix init code will not be executed. This is equivalent to current code. With this, the code only setups single mode msix as a last resort if msi fails. No interrupt range is enabled at all. Only one interrupt will be enabled. tj: comment edits. Changes of the patch series: v5: * updated patch subject that the patch only implements single IRQ * moved Cavium specific code to a separate patch * detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI instead of vendor/dev id * added more comments to the code * enable single msix support for all kind of devices (removing strict check) * rebased onto update libata/for-4.2 with patch 1, 2 applied v4: * removed implementation of ahci_init_intx() * improved patch descriptions * rebased onto libata/for-4.2 v3: * store irq number in struct ahci_host_priv * change initialization order from msix-msi-intx to msi-msix-intx * improve comments in ahci_init_msix() * improve error message in ahci_init_msix() * do not enable MSI-X if MSI is actively disabled for the device v2: * determine irq vector from pci_dev->msi_list Based on a patch from Sunil Goutham <sgoutham@cavium.com>.

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: NRobert Richter <rrichter@cavium.com> Signed-off-by: NTejun Heo <tj@kernel.org>

Brian noticed while working on another SATA driver that uses libahci_platform, an error in this driver; it tries to the the driver data for its device, while libata also thinks it can set the driver data. See: ahci_platform_init_host() -> ata_host_alloc_pinfo() -> ata_host_alloc() -> dev_set_drvdata() So instead of sticking the IP-specific platform data into drvdata, let's use the plat_data variable that is reserved for this use. Addtionally plat_data isn't set until ahci_platform_init_host() has been called further down in probe(). So re-work the st_ahci_probe_resets and st_ahci_deassert_resets functions to take ahci_host_priv *hpriv as a parameter.

Pull regulator updates from Mark Brown: "Another release, another set of regulator updates. Not much of it is showing up in the code yet but there's been a lot of discussion going on about how to enhance the regulator API to work better with modern SoCs which have a microcontroller sitting between Linux and the hardware. I'm hopeful that'll start to come through into mainline for v4.2 but it's not quite there for v4.1 - what we do have (along with the usual small updates is) is: - work from Bjorn Andersson on refactoring the configuration of regulator loading interfaces to be useful for use with microcontrollers, the existing interfaces were never actually useful for anything as-is since nobody was willing to put enough data into public code. - a summary tree display in debugfs from Heiko Stübner. - support for act6000 regulators" * tag 'regulator-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (34 commits) regulator: max8660: Handle empty regulator data regulator: output current-limit for all regulators in summary regulator: add a summary tree in debugfs regulator: qcom: Tidy up probe() regulator: qcom: Rework to single platform device regulator: qcom: Refactor of-parsing code regulator: qcom: Don't enable DRMS in driver regulator: max8660: fix assignment of pdata to data that becomes dead regulator: Defer lookup of supply to regulator_get mfd: max77693: Remove unused structures regulator: max77693: Let core parse DT and drop board files support regulator: Ensure unique regulator debugfs directory names regulator: stw481x: Remove unused fields from struct stw481x regulator: palmas: Add has_regen3 check for TPS659038 regulator: constify of_device_id array regulator: fixes for regulator_set_optimum_mode name change regulator: Drop temporary regulator_set_optimum_mode wrapper usb: phy: phy-msm-usb: Rename regulator_set_optimum_mode usb: phy: ab8500-usb: Rename regulator_set_optimum_mode ufs: Rename of regulator_set_optimum_mode ...
