dma:dw: remove reference to AVR32 architecture in core.c

2022-08-03T09:03:02Z

The AVR32 architecture does no longer exist in the Linux kernel, hence remove a reference to it in comments to avoid confusion. Signed-off-by: Hans-Christian Noren Egtvedt

dmaengine: dw: dmamux: Fix build without CONFIG_OF

2022-06-10T12:21:21Z

When built without OF support, of_match_node() expands to NULL, which produces the following output: >> drivers/dma/dw/rzn1-dmamux.c:105:34: warning: unused variable 'rzn1_dmac_match' [-Wunused-const-variable] static const struct of_device_id rzn1_dmac_match[] = { One way to silence the warning is to enclose the structure definition with an #ifdef CONFIG_OF/#endif block.

dmaengine: dw: dmamux: Export the module device table

This is a tristate driver that can be built as a module, as a result, the OF match table should be exported with MODULE_DEVICE_TABLE().

dmaengine: dw: Add RZN1 compatible

The Renesas RZN1 DMA IP is very close to the original DW DMA IP, a DMA router has been introduced to handle the wiring options that have been added.

dmaengine: dw: dmamux: Introduce RZN1 DMA router support

2022-05-19T17:04:51Z

The Renesas RZN1 DMA IP is based on a DW core, with eg. an additional dmamux register located in the system control area which can take up to 32 requests (16 per DMA controller). Each DMA channel can be wired to two different peripherals. We need two additional information from the 'dmas' property: the channel (bit in the dmamux register) that must be accessed and the value of the mux for this channel.

dmaengine: dw: switch from 'pci_' to 'dma_' API

2021-10-26T05:24:32Z

The wrappers in include/linux/pci-dma-compat.h should go away. pci_set_dma_mask()/pci_set_consistent_dma_mask() should be replaced with dma_set_mask()/dma_set_coherent_mask(), and use dma_set_mask_and_coherent() for both.

dmaengine: dw: Simplify DT property parser

Since we converted internal data types to match DT, there is no need to have an intermediate conversion layer, hence drop a few conditionals and for loops for good.

Users are a bit frightened of the harmless message that tells that DT is missed on ACPI-based platforms. Remove it for good, it will simplify the future conversion to fwnode and device property APIs.

dmaengine: dw: Program xBAR hardware for Elkhart Lake

2021-07-14T04:46:30Z

Intel Elkhart Lake PSE DMA implementation is integrated with crossbar IP in order to serve more hardware than there are DMA request lines available. Due to this, program xBAR hardware to make flexible support of PSE peripheral. The Device-to-Device has not been tested and it's not supported by DMA Engine, but it's left in the code for the sake of documenting hardware features.
