2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring1-1/+0
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

This option when turned on, replaces all page 1 offsets used for EVTQ_PROD/CONS, PRIQ_PROD/CONS register access with page 0 offsets. SMMU resource size checks are now based on SMMU option PAGE0_REGS_ONLY, since resource size can be either 64k/128k. For this, arm_smmu_device_dt_probe/acpi_probe has been moved before platform_get_resource call, so that SMMU options are set beforehand.

2017-04-06iommu/arm-smmu: Add global SMR masking propertyRobin Murphy1-0/+28
The current SMR masking support using a 2-cell iommu-specifier is primarily intended to handle individual masters with large and/or complex Stream ID assignments; it quickly gets a bit clunky in other SMR use-cases where we just want to consistently mask out the same part of every Stream ID (e.g. for MMU-500 configurations where the appended TBU number gets in the way unnecessarily). Let's add a new property to allow a single global mask value to better fit the latter situation.

2017-01-09Docs: dt: Be explicit and consistent in reference to IOMMU specifiersStuart Yoder1-5/+5
The generic IOMMU binding says that the meaning of an 'IOMMU specifier' is defined by the binding of a specific SMMU. The ARM SMMU binding never explicitly uses the term 'specifier' at all. Update implicit references to use the explicit term. In the iommu-map binding change references to iommu-specifier to "IOMMU specifier" so we are 100% consistent everywhere with terminology and capitalization.

2015-07-31iommu/arm-smmu: Sort out coherencyRobin Murphy1-0/+6
Currently, we detect whether the SMMU has coherent page table walk capability from the IDR0.CTTW field, and base our cache maintenance decisions on that. In preparation for fixing the bogus DMA API usage, however, we need to ensure that the DMA API agrees about this, which necessitates deferring to the dma-coherent property in the device tree for the final say. As an added bonus, since systems exist where an external CTTW signal has been tied off incorrectly at integration, allowing DT to override it offers a neat workaround for coherency issues with such SMMUs.

2015-07-08iommu/arm-smmu: Skip the execution of CMD_PREFETCH_CONFIGZhen Lei1-0/+3
Hisilicon SMMUv3 devices treat CMD_PREFETCH_CONFIG as a illegal command, execute it will trigger GERROR interrupt. Although the gerror code manage to turn the prefetch into a SYNC, and the system can continue to run normally, but it's ugly to print error information.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC DT updates from Olof Johansson: "DT changes continue to be the bulk of our merge window contents. We continue to have a large set of changes across the board as new platforms and drivers are added. Some of the new platforms are: - Alphascale ASM9260 - Marvell Armada 388 - CSR Atlas7 - TI Davinci DM816x - Hisilicon HiP01 - ST STiH418 There have also been some sweeping changes, including relicensing of DTS contents from GPL to GPLv2+/X11 so that the same files can be reused in other non-GPL projects more easily. There's also been changes to the DT Makefile to make it a little less conflict-ridden and churny down the road" * tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (330 commits) ARM: dts: Add PPMU node for exynos4412-trats2 ARM: dts: Add PPMU node for exynos3250-monk and exynos3250-rinato ARM: dts: Add PPMU dt node for exynos4 and exynos4210 ARM: dts: Add PPMU dt node for exynos3250 ARM: dts: add mipi dsi device node for exynos4415 ARM: dts: add fimd device node for exynos4415 ARM: dts: Add syscon phandle to the video-phy node for Exynos4 ARM: dts: Add sound nodes for exynos4412-trats2 ARM: dts: Fix CLK_MOUT_CAMn parent clocks assignment for exynos4412-trats2 ARM: dts: Fix CLK_UART_ISP_SCLK clock assignment in exynos4x12.dtsi ARM: dts: Add max77693 charger node for exynos4412-trats2 ARM: dts: Switch max77686 regulators to GPIO control for exynos4412-trats2 ARM: dts: Add suspend configuration for max77686 regulators for exynos4412-trats2 ARM: dts: Add Maxim 77693 fuel gauge node for exynos4412-trats2 ARM: dts: am57xx-beagle-x15: Fix USB2 mode ARM: dts: am57xx-beagle-x15: Add extcon nodes for USB ARM: dts: dra72-evm: Add extcon nodes for USB ARM: dts: dra7-evm: Add extcon nodes for USB ARM: dts: rockchip: move the hdmi ddc-i2c-bus property to the actual boards ARM: dts: rockchip: enable vops and hdmi output on rk3288-firefly and -evb ...
