git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "Slightly more changes than usual this time: - KDump Kernel IOMMU take-over code for AMD IOMMU. The code now tries to preserve the mappings of the kernel so that master aborts for devices are avoided. Master aborts cause some devices to fail in the kdump kernel, so this code makes the dump more likely to succeed when AMD IOMMU is enabled. - common flush queue implementation for IOVA code users. The code is still optional, but AMD and Intel IOMMU drivers had their own implementation which is now unified. - finish support for iommu-groups. All drivers implement this feature now so that IOMMU core code can rely on it. - finish support for 'struct iommu_device' in iommu drivers. All drivers now use the interface. - new functions in the IOMMU-API for explicit IO/TLB flushing. This will help to reduce the number of IO/TLB flushes when IOMMU drivers support this interface. - support for mt2712 in the Mediatek IOMMU driver - new IOMMU driver for QCOM hardware - system PM support for ARM-SMMU - shutdown method for ARM-SMMU-v3 - some constification patches - various other small improvements and fixes" * tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (87 commits) iommu/vt-d: Don't be too aggressive when clearing one context entry iommu: Introduce Interface for IOMMU TLB Flushing iommu/s390: Constify iommu_ops iommu/vt-d: Avoid calling virt_to_phys() on null pointer iommu/vt-d: IOMMU Page Request needs to check if address is canonical. arm/tegra: Call bus_set_iommu() after iommu_device_register() iommu/exynos: Constify iommu_ops iommu/ipmmu-vmsa: Make ipmmu_gather_ops const iommu/ipmmu-vmsa: Rereserving a free context before setting up a pagetable iommu/amd: Rename a few flush functions iommu/amd: Check if domain is NULL in get_domain() and return -EBUSY iommu/mediatek: Fix a build warning of BIT(32) in ARM iommu/mediatek: Fix a build fail of m4u_type iommu: qcom: annotate PM functions as __maybe_unused iommu/pamu: Fix PAMU boot crash memory: mtk-smi: Degrade SMI init to module_init iommu/mediatek: Enlarge the validate PA range for 4GB mode iommu/mediatek: Disable iommu clock when system suspend iommu/mediatek: Move pgtable allocation into domain_alloc iommu/mediatek: Merge 2 M4U HWs into one iommu domain ...

platform_get_resource() may fail, so we should better check its return value and propagate an error in case it fails. This avoids a NULL pointer dereference a bit later in the code.

2017-09-09watchdog: renesas_wdt: apply better precisionWolfram Sang1-9/+19
The error margin of the clks_per_second variable was too large and caused offsets when used with clock frequencies which left a remainder after applying the dividers. Now we always calculate directly using the clock rate and the divider using some helper macros. That also means that DIV_ROUND_UP moves from probe to the multiplication macro. In probe, we don't need to ensure anymore that 'clks_per_sec' would go too fast but rather ensure that the lower limit is really at least 1 to certainly get a full cycle.

The watchdog IP block on Meson8 and Meson8m2 is already supported by the existing meson-wdt driver. Meson8 uses the same register bits as Meson6, while the newer Meson8m2 SoC uses the same register bits as Meson8b. Currently watchdog support on Meson8 SoC already works because meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a separate compatible for Meson8 makes this more explicit though.
