Merge tag 'iommu-updates-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

2020-10-14T19:08:34Z

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 ...

regulator: qcom_smd: Add PM660/PM660L regulator support

2020-10-01T20:25:25Z

The PM660 and PM660L are a very very common PMIC combo, found on boards using the SDM630, SDM636, SDM660 (and SDA variants) SoC. PM660 provides 6 SMPS and 19 LDOs (of which one is unaccesible), while PM660L provides 5 SMPS (of which S3 and S4 are combined), 10 LDOs and a Buck-or-Boost (BoB) regulator. The PM660L IC also provides other regulators that are very specialized (for example, for the display) and will be managed in the other appropriate drivers (for example, labibb).

iommu/mediatek: Check 4GB mode by reading infracfg

2020-09-04T11:20:36Z

In previous discussion [1] and [2], we found that it is risky to use max_pfn or totalram_pages to tell if 4GB mode is enabled. Check 4GB mode by reading infracfg register, remove the usage of the un-exported symbol max_pfn. This is a step towards building mtk_iommu as a kernel module.

firmware: ti_sci: Add support for getting resource with subtype

2020-08-16T21:00:22Z

With SYSFW ABI 3.0 changes, interrupts coming out of an interrupt controller is identified by a type and it is consistent across SoCs. Similarly global events for Interrupt aggregator. So add an API to get resource range using a resource type.

soc: ti: k3-ringacc: add request pair of rings api.

2020-07-24T21:19:12Z

Add new API k3_ringacc_request_rings_pair() to request pair of rings at once, as in the most cases Rings are used with DMA channels, which need to request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and one to receive completions (RX/TX CQ). This will allow to simplify Ringacc API users. Signed-off-by: Grygorii Strashko Reviewed-by: Peter Ujfalusi Signed-off-by: Santosh Shilimkar
