git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers Memory controller drivers for v5.11 - Tegra SoC, part two Continuation of work on Tegra SoC memory controllers towards adding interconnect support and integration with devfreq. This brings few more patches including one which removes/fixes annoying warning if the DTS patches get applied. This is expected and only informs that new features of Tegra memory controller drivers will not be enabled however the warning itself could look worrying. * tag 'memory-controller-drv-tegra-5.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: memory: tegra30: Support interconnect framework memory: tegra20: Support hardware versioning and clean up OPP table initialization dt-bindings: memory: tegra20-emc: Document opp-supported-hw property Link: https://lore.kernel.org/r/20201207075758.5501-2-krzk@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - ARM-SMMU Updates from Will: - Continued SVM enablement, where page-table is shared with CPU - Groundwork to support integrated SMMU with Adreno GPU - Allow disabling of MSI-based polling on the kernel command-line - Minor driver fixes and cleanups (octal permissions, error messages, ...) - Secure Nested Paging Support for AMD IOMMU. The IOMMU will fault when a device tries DMA on memory owned by a guest. This needs new fault-types as well as a rewrite of the IOMMU memory semaphore for command completions. - Allow broken Intel IOMMUs (wrong address widths reported) to still be used for interrupt remapping. - IOMMU UAPI updates for supporting vSVA, where the IOMMU can access address spaces of processes running in a VM. - Support for the MT8167 IOMMU in the Mediatek IOMMU driver. - Device-tree updates for the Renesas driver to support r8a7742. - Several smaller fixes and cleanups all over the place. * tag 'iommu-updates-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (57 commits) iommu/vt-d: Gracefully handle DMAR units with no supported address widths iommu/vt-d: Check UAPI data processed by IOMMU core iommu/uapi: Handle data and argsz filled by users iommu/uapi: Rename uapi functions iommu/uapi: Use named union for user data iommu/uapi: Add argsz for user filled data docs: IOMMU user API iommu/qcom: add missing put_device() call in qcom_iommu_of_xlate() iommu/arm-smmu-v3: Add SVA device feature iommu/arm-smmu-v3: Check for SVA features iommu/arm-smmu-v3: Seize private ASID iommu/arm-smmu-v3: Share process page tables iommu/arm-smmu-v3: Move definitions to a header iommu/io-pgtable-arm: Move some definitions to a header iommu/arm-smmu-v3: Ensure queue is read after updating prod pointer iommu/amd: Re-purpose Exclusion range registers to support SNP CWWB iommu/amd: Add support for RMP_PAGE_FAULT and RMP_HW_ERR iommu/amd: Use 4K page for completion wait write-back semaphore iommu/tegra-smmu: Allow to group clients in same swgroup iommu/tegra-smmu: Fix iova->phys translation ...
2020-09-29PM / devfreq: event: Change prototype of devfreq_event_get_edev_by_phandle ↵Chanwoo Choi1-2/+4
function Previously, devfreq core support 'devfreq-events' property in order to get the devfreq-event device by phandle. But, 'devfreq-events' property name is not proper on devicetree binding because this name doesn't mean the any h/w attribute. The devfreq-event core hand over the rights to decide the property name for getting the devfreq-event device on devicetree. Each devfreq-event driver will decide the property name on devicetree binding and then pass the their own property name to devfreq_event_get_edev_by_phandle function. And change the prototype of devfreq_event_get_edev_count function because of used deprecated 'devfreq-events' property.

Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code. Along with this change, we get additionally: .owner = THIS_MODULE, .llseek = seq_lseek, 1. The llseek method is used to change the current read/write position in a file which can be ignored if you don't use it. 2. The owner is not even a method. Instead, it is a pointer to the module that “owns” this structure; it is used by the kernel to maintain the module's usage count which can be ignored.

2020-09-02memory: tegra: Remove GPU from DRM IOMMU groupThierry Reding1-1/+0
Commit 63a613fdb16c ("memory: tegra: Add gr2d and gr3d to DRM IOMMU group") added the GPU to the DRM IOMMU group, which doesn't make any sense. This causes problems when Nouveau tries to attach to the SMMU and causes it to fall back to using the DMA API. Remove the GPU from the DRM groups to restore the old behaviour. The GPU should always have its own IOMMU domain to make sure it can map buffers into contiguous chunks (for big page support) without getting in the way of mappings from the DRM group.
