2016-11-08scsi: ufshcd: Fix possible unclocked register accessSubhash Jadavani3-16/+19
Vendor specific setup_clocks callback may require the clocks managed by ufshcd driver to be ON. So if the vendor specific setup_clocks callback is called while the required clocks are turned off, it could result into unclocked register access. To prevent possible unclock register access, this change adds one more argument to setup_clocks callback to let it know whether it is called pre/post the clock changes by core driver.

If we haven't logged into the fabric yet we want to be a little more nuanced with our CVL handling than what we've been: - If the FCF has been selected, check the source MAC to make sure the frame is from the FCF we've selected. - If a FCF is selected and the CVL is from the FCF but we have not logged in yet, then reset everything and go back to solicitation.

The list of attached 'rdata' remote port structures is RCU protected, so there is no need to take the 'disc_mutex' when traversing it. Rather we should be using rcu_read_lock() and kref_get_unless_zero() to validate the entries. We need, however, take the disc_mutex when deleting an entry; otherwise we risk clashes with list_add.

2016-11-08scsi: hisi_sas: Add v2 hw support for different refclkJohn Garry3-1/+12
The hip06 D03 and hip07 D05 boards have different reference clock frequencies for the SAS controller. Register PHY_CTRL needs to be programmed differently according to this frequency, so add support for this. The default register setting in PHY_CTRL is for 50MHz, so only update this register when the refclk frequency is 66MHz. For ACPI we expect the _RST handler to set the correct value for PHY_CTRL (we're forced to take different approach for DT and ACPI as ACPI does not support fixed-clock device).

2016-11-08iommu/arm-smmu: Fix out-of-bounds dereferenceRobin Murphy1-1/+3
When we iterate a master's config entries, what we generally care about is the entry's stream map index, rather than the entry index itself, so it's nice to have the iterator automatically assign the former from the latter. Unfortunately, booting with KASAN reveals the oversight that using a simple comma operator results in the entry index being dereferenced before being checked for validity, so we always access one element past the end of the fwspec array. Flip things around so that the check always happens before the index may be dereferenced.

2016-11-08iommu/arm-smmu: Don't inadvertently reject multiple SMMUv3sRobin Murphy1-8/+17
We now delay installing our per-bus iommu_ops until we know an SMMU has successfully probed, as they don't serve much purpose beforehand, and doing so also avoids fights between multiple IOMMU drivers in a single kernel. However, the upshot of passing the return value of bus_set_iommu() back from our probe function is that if there happens to be more than one SMMUv3 device in a system, the second and subsequent probes will wind up returning -EBUSY to the driver core and getting torn down again. Avoid re-setting ops if ours are already installed, so that any genuine failures stand out.

2016-11-08iommu/arm-smmu: Work around ARM DMA configurationRobin Murphy1-0/+10
The 32-bit ARM DMA configuration code predates the IOMMU core's default domain functionality, and instead relies on allocating its own domains and attaching any devices using the generic IOMMU binding to them. Unfortunately, it does this relatively early on in the creation of the device, before we've seen our add_device callback, which leads us to attempt to operate on a half-configured master. To avoid a crash, check for this situation on attach, but refuse to play, as there's nothing we can do. This at least allows VFIO to keep working for people who update their 32-bit DTs to the generic binding, albeit with a few (innocuous) warnings from the DMA layer on boot.

We're going to try a group maintainership model, so eventually you'll probably see pull requests from people besides me. - NAND fixes from Boris: "Three simple fixes: - fix a non-critical bug in the gpmi driver - fix a bug in the 'automatic NAND timings selection' feature introduced in 4.9-rc1 - fix a false positive uninitialized-var warning" * tag 'for-linus-20161104' of git://git.infradead.org/linux-mtd: mtd: mtk: avoid warning in mtk_ecc_encode mtd: nand: Fix data interface configuration logic mtd: nand: gpmi: disable the clocks on errors MAINTAINERS: add more people to the MTD maintainer team MAINTAINERS: add a maintainer for the SPI NOR subsystem

2016-11-05HID: sensor: fix attributes in HID sensor interfaceOoi, Joyce1-3/+3
User is unable to access to input-X-yyy and feature-X-yyy where X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID sensor custom sysfs interface. This is because when creating the attribute, the attribute index is written to using %x (hex). However, when reading and writing values into the attribute, the attribute index is scanned using %d (decimal). Hence, user is unable to access to attributes with index in hex values (e.g. 'a', 'b', 'c') but able to access to attributes with index in decimal values (e.g. 1, 2, 3,..). This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s and feature-%x-%x-%s in show_values() and store_values() accordingly.

2016-11-05HID: intel-ish-hid: request_irq failureSrinivas Pandruvada1-1/+1
On some platforms ISH interrupt is shared, which causes request_irq to fail. This requires IRQF_SHARED irq flag. But IRQF_NO_SUSPEND and IRQF_SHARED should not be used together, so removed IRQF_NO_SUSPEND flag. Anyway this driver doesn't require IRQF_NO_SUSPEND, as this interrupt is not required during "noirq" phases of suspending and resuming devices as well as during the time when nonboot CPUs are taken offline and brought back online.

2016-11-05HID: intel-ish-hid: Fix driver reinit failureEven Xu1-0/+15
When built as a module, modprobe followed by rmmod can fail because DMA was still active. So to fix this, DMA needs to be disabled during module exit. This change disables DMA during modules exit and change the ISH PCI device status to D3.

2016-11-04PCI: designware: Check for iATU unroll support after initializing hostNiklas Cassel1-2/+5
dw_pcie_iatu_unroll_enabled() reads a dbi_base register. Reading any dbi_base register before pp->ops->host_init has been called causes "imprecise external abort" on platforms like ARTPEC-6, where the PCIe module is disabled at boot and first enabled in pp->ops->host_init. Move dw_pcie_iatu_unroll_enabled() to dw_pcie_setup_rc(), since it is after pp->ops->host_init, but before pp->iatu_unroll_enabled is actually used.
