Merge tag 'scmi-updates-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers Arm SCMI firmware driver updates/fixes for v5.19 The main theme for most of the changes this time is around the addition of the support for SCMI v3.1 specification changes. Though one of the main addition in the specification is the powercap protocol, that is still work in progress and this set includes all other changes bit and pieces scattered all around the different parts of the specification. There are few bugs discovered during the process and associated fixes and some refactoring to simplify the addition of v3.1 support. It mainly includes the support for extended names, few newly added notifications and async command support. Apart from v3.1 SCMI changes, OPTEE transport gets support for dynamic shared memory. * tag 'scmi-updates-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (24 commits) firmware: arm_scmi: Fix late checks on pointer dereference firmware: arm_scmi: Support optee shared memory in the optee transport firmware: arm_scmi: Add SCMI v3.1 VOLTAGE_LEVEL_SET_COMPLETE firmware: arm_scmi: Add SCMI v3.1 clock notifications firmware: arm_scmi: Add checks for min/max limits in PERFORMANCE_LIMITS_SET firmware: arm_scmi: Add SCMI v3.1 perf power-cost in microwatts firmware: arm_scmi: Use common iterators in the perf protocol firmware: arm_scmi: Use common iterators in the voltage protocol firmware: arm_scmi: Use common iterators in the clock protocol firmware: arm_scmi: Add SCMI v3.1 SENSOR_AXIS_NAME_GET support firmware: arm_scmi: Use common iterators in the sensor protocol firmware: arm_scmi: Add iterators for multi-part commands firmware: arm_scmi: Parse clock_enable_latency conditionally firmware: arm_scmi: Set clock latency to U32_MAX if it is not supported firmware: arm_scmi: Add SCMI v3.1 protocol extended names support firmware: arm_scmi: Introduce a common SCMI v3.1 .extended_name_get helper firmware: arm_scmi: Split protocol specific definitions in a dedicated header firmware: arm_scmi: Remove unneeded NULL termination of clk name firmware: arm_scmi: Check CLOCK_RATE_SET_COMPLETE async response firmware: arm_scmi: Make name_get operations return a const ...

Apple SoCs such as the M1 come with an embedded NVMe coprocessor called ANS2. Reviewed-by:

Sven Peter authored
The NVMe co-processor on the Apple M1 uses a DMA address filter called SART for some DMA transactions. This adds a simple driver used to configure the memory regions from which DMA transactions are allowed. Unlike a real IOMMU, SART does not support any pagetables and can't be implemented inside the IOMMU subsystem using iommu_ops. It also can't be implemented using dma_map_ops since not all DMA transactions of the NVMe controller are filtered by SART. Instead, most buffers have to be registered using the integrated NVMe IOMMU and we can't have two separate dma_map_ops implementations for a single device. Co-developed-by:
