2023-08-22dmaengine: fsl-edma: refactor using devm_clk_get_enabledFrank Li
Use devm_clk_get_enabled in probe code to reduce error checks, thereby enhancing readability Signed-off-by: Frank Li <Frank.Li@nxp.com> Link: https://lore.kernel.org/r/20230821161617.2142561-8-Frank.Li@nxp.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
2023-08-22dmaengine: fsl-edma: simply ATTR_DSIZE and ATTR_SSIZE by using ffs()Frank Li
Removes all ATTR_DSIZE_*BIT(BYTE) and ATTR_SSIZE_*BIT(BYTE) definitions in edma. Uses ffs() instead, as it gives identical results. This simplifies the code and avoids adding more similar definitions in future V3 version.

2023-08-22dmaengine: fsl-edma: Remove enum edma_versionFrank Li
The enum edma_version, which defines v1, v2, and v3, is a software concept used to distinguish IP differences. However, it is not aligned with the chip reference manual. According to the 7ulp reference manual, it should be edma2. In the future, there will be edma3, edma4, and edma5, which could cause confusion. To avoid this confusion, remove the edma_version and instead use drvdata->flags to distinguish the IP difference.

2023-08-21dmaengine: idxd: Fix issues with PRS disable sysfs knobFenghua Yu
There are two issues in the current PRS disable sysfs store function wq_prs_disable_store(): 1. Since PRS disable knob is invisible if PRS disable is not supported in WQ, it's redundant to check PRS support again in the store function again. Remove the redundant PRS support check. 2. Since PRS disable is read-only when the device is not configurable, PRS disable cannot be changed on the device. Add device configurable check in the store function.

2023-08-21dmaengine: xilinx_dma: Program interrupt delay timeoutRadhey Shyam Pandey
Program IRQDelay for AXI DMA. The interrupt timeout mechanism causes the DMA engine to generate an interrupt after the delay time period has expired. It enables dmaengine to respond in real-time even though interrupt coalescing is configured. It also remove the placeholder for delay interrupt and merge it with frame completion interrupt. Since by default interrupt delay timeout is disabled this feature addition has no functional impact on VDMA, MCDMA and CDMA IP's.

2023-08-21dt-bindings: dmaengine: xilinx_dma: Add xlnx,irq-delay propertyRadhey Shyam Pandey
Add an optional AXI DMA property 'xlnx,irq-delay'. It specifies interrupt timeout value and causes the DMA engine to generate an interrupt after the delay time period has expired. Timer begins counting at the end of a packet and resets with receipt of a new packet or a timeout event occurs. This property is useful when AXI DMA is connected to the streaming IP i.e axiethernet where inter packet latency is critical while still taking the benefit of interrupt coalescing.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

2023-07-12dt-bindings: dma: Increase iommu maxItems for BAM DMABhupesh Sharma
Since SM8250 BAM DMA engine supports six iommu entries, increase the maxItems in the iommu property section, without which 'dtbs_check' would throw errors.

2023-07-12dt-bindings: dma: Add support for SM6115 and QCM2290 SoCsBhupesh Sharma
Add new compatible for BAM DMA engine version v1.7.4 which is found on Qualcomm SM6115 and QCM2290 SoCs. Since its very similar to v1.7.0 used on SM8150 like SoCs, mark the comptible scheme accordingly. While at it, also update qcom,bam-dma bindings to add comments which describe the BAM DMA versions used in SM8150 and SM8250 SoCs. This provides an easy reference for identifying the actual BAM DMA version available on Qualcomm SoCs.

We usually do cleanup in reverse order of init. Currently, in the case of error, this is not followed in rz_dmac_probe(), and similar case for remove(). This patch improves error handling in probe() and cleanup in reverse order of init in the remove().

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair.
