dmaengine: drivers: Kconfig: add HAS_IOMEM dependency to DW_AXI_DMAC

2021-02-01T09:38:15+00:00

If HAS_IOMEM is not defined and DW_AXI_DMAC is enabled under COMPILE_TEST,
the build fails with the following error:
dw-axi-dmac-platform.c:(.text+0xc4): undefined reference to
`devm_ioremap_resource'

There is no reason the Marvell MMP two-channel audio DMA driver would have
to be built-in.

dmaengine: Add Intel LGM SoC DMA support.

2021-01-12T12:28:32+00:00

Add DMA controller driver for Lightning Mountain (LGM) family of SoCs.

The main function of the DMA controller is the transfer of data from/to any
peripheral to/from the memory. A memory to memory copy capability can also
be configured.

This ldma driver is used for configure the device and channnels for data
and control paths.

dmaengine: idxd: Add shared workqueue support

2020-10-30T08:40:36+00:00

Add shared workqueue support that includes the support of Shared Virtual
memory (SVM) or in similar terms On Demand Paging (ODP). The shared
workqueue uses the enqcmds command in kernel and will respond with retry if
the workqueue is full. Shared workqueue only works when there is PASID
support from the IOMMU.

misc: mic: remove the MIC drivers

2020-10-28T18:12:03+00:00

This patch removes the MIC drivers from the kernel tree
since the corresponding devices have been discontinued.

Removing the dma and char-misc changes in one patch and
merging via the char-misc tree is best to avoid any
potential build breakage.
