bus: fsl-mc: use raw spin lock to serialize mc cmds

2020-07-23T14:54:33Z

Replace the spinlock that serializes the MC commands with a raw spinlock. This is needed for the RT kernel because there are MC commands sent in interrupt context.

bus: fsl-mc: add api to retrieve mc version

2020-03-30T00:50:49Z

Add a new api that returns Management Complex firmware version and make the required structure public. The api's first user will be the caam driver for setting prediction resistance bits.

bus: fsl-mc: add the fsl_mc_get_endpoint function

2019-10-31T21:19:45Z

Using the newly added fsl_mc_get_endpoint function a fsl-mc driver can find its associated endpoint (another object at the other link of a MC firmware link). The API will be used in the following patch in order to discover the connected DPMAC object of a DPNI. Also, the fsl_mc_device_lookup function is made available to the entire fsl-mc bus driver and not just for the dprc driver. Signed-off-by: Ioana Ciornei Signed-off-by: David S. Miller

bus: fsl-mc: automatically add a device_link on fsl_mc_[portal,object]_allocate

2019-01-11T21:06:54Z

Allocatable devices can be acquired by drivers on the fsl-mc bus using the fsl_mc_portal_allocate or fsl_mc_object_allocate functions. Add a device link between the consumer device and the supplier device so that proper resource management is achieved. Also, adding a link between these devices ensures that a proper unbind order is respected (ie before the supplier device is unbound from its respective driver all consumer devices will be notified and unbound first).

Pull IOMMU updates from Joerg Roedel: - Debugfs support for the Intel VT-d driver. When enabled, it now also exposes some of its internal data structures to user-space for debugging purposes. - ARM-SMMU driver now uses the generic deferred flushing and fast-path iova allocation code. This is expected to be a major performance improvement, as this allocation path scales a lot better. - Support for r8a7744 in the Renesas iommu driver - Couple of minor fixes and improvements all over the place * tag 'iommu-updates-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (39 commits) iommu/arm-smmu-v3: Remove unnecessary wrapper function iommu/arm-smmu-v3: Add SPDX header iommu/amd: Add default branch in amd_iommu_capable() dt-bindings: iommu: ipmmu-vmsa: Add r8a7744 support iommu/amd: Move iommu_init_pci() to .init section iommu/arm-smmu: Support non-strict mode iommu/io-pgtable-arm-v7s: Add support for non-strict mode iommu/arm-smmu-v3: Add support for non-strict mode iommu/io-pgtable-arm: Add support for non-strict mode iommu: Add "iommu.strict" command line option iommu/dma: Add support for non-strict mode iommu/arm-smmu: Ensure that page-table updates are visible before TLBI iommu/arm-smmu-v3: Implement flush_iotlb_all hook iommu/arm-smmu-v3: Avoid back-to-back CMD_SYNC operations iommu/arm-smmu-v3: Fix unexpected CMD_SYNC timeout iommu/io-pgtable-arm: Fix race handling in split_blk_unmap() iommu/arm-smmu-v3: Fix a couple of minor comment typos iommu: Fix a typo iommu: Remove .domain_{get,set}_windows iommu: Tidy up window attributes ...
