Pull MIPS updates from Ralf Baechle: "This is the main pull request for 4.3 for MIPS. Here's the summary: Three fixes that didn't make 4.2-stable: - a -Os build might compile the kernel using the MIPS16 instruction set but the R2 optimized inline functions in <uapi/asm/swab.h> are implemented using 32-bit wide instructions which is invalid. - a build error in pgtable-bits.h for a particular kernel configuration. - accessing registers of the CM GCR might have been compiled to use 64 bit accesses but these registers are onl 32 bit wide. And also a few new bits: - move the ATH79 GPIO driver to drivers/gpio - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h, change ATH79 accordingly. - fix definition of pgprot_writecombine - add an implementation of dma_map_ops.mmap - fix alignment of quiet build output for vmlinuz link - BCM47xx: Use kmemdup rather than duplicating its implementation - Netlogic: Fix 0x0x prefixes of constants. - merge Bjorn Helgaas' series to remove most of the weak keywords from function declarations. - CP0 and CP1 registers are best considered treated as unsigned values to avoid large values from becoming negative values. - improve support for the MIPS GIC timer. - enable common clock framework for Malta and SEAD3. - a number of improvments and fixes to dump_tlb(). - document the MIPS TLB dump functionality in Magic SysRq. - Cavium Octeon CN68XX improvments. - NetLogic improvments. - irq: Use access helper irq_data_get_affinity_mask. - handle MSA unaligned accesses. - a number of R6-related math-emu fixes. - support for I6400. - improvments to MSA support. - add uprobes support. - move from deprecated __initcall to arch_initcall. - remove finish_arch_switch(). - IRQ cleanups by Thomas Gleixner. - migrate to new 'set-state' interface. - random small cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (148 commits) MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel1-2/+1
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

2015-08-24PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCIZhang Rui2-24/+1
On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at function 1 doesn't work if it is powered on before the SATA controller at function 0. The result is that PATA doesn't work after resume, and we print messages like this: pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3 irq 17: nobody cared (try booting with the "irqpoll" option) Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep: Asynchronous threads for resume_noirq"). Prior to that, we powered on the functions in order, so this problem shouldn't happen. e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361") solved the problem for JMicron 361 and 363 devices. With async suspend disabled, we always power on function 0 before function 1. Barto then reported the same problem with a JMicron 368 (see comment #57 in the bugzilla). Rather than extending the blacklist piecemeal, disable async suspend for all JMicron multi-function SATA/PATA/AHCI devices. This quirk could stay in the ahci and pata_jmicron drivers, but it's likely the problem will occur even if pata_jmicron isn't loaded until after the suspend/resume. Making it a PCI quirk ensures that we'll preserve the power-on order even if the drivers aren't loaded.

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.

Queued TRIM got disabled on Micron M500DC drives thanks to the "Micron_M500*" pattern we had in place to accommodate the previous generation of this drive family.

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.

2015-06-16ahci: Add support for Cavium's ThunderX host controllerRobert Richter1-1/+4
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.

2015-06-16ahci: Add generic MSI-X support for single interrupts to SATA PCI driverRobert Richter1-0/+72
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>.

2015-06-03ahci: Store irq number in struct ahci_host_privRobert Richter6-19/+27
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.

According to the Armada 38x datasheet, the window base address registers value is set in bits [31:4] of the register and corresponds to the transaction address bits [47:20]. Therefore, the 32bit base address value should be shifted right by 20bits and left by 4bits, resulting in 16 bit shift right. The bug as not been noticed yet because if the memory available on the platform is less than 2GB, then the base address is zero.
