[PATCH v3 0/5] Add eDMAv3 support for S32G2/S32G3 SoCs

[PATCH v3 0/5] Add eDMAv3 support for S32G2/S32G3 SoCs

[Larisa Grigore]

S32G2 and S32G3 SoCs share the eDMAv3 module with i.MX SoCs, with some hardware
integration particularities.

S32G2/S32G3 includes two system eDMA instances based on v3 version, each of
them integrated with 2 DMAMUX blocks.
Another particularity of these SoCs is that the interrupts are shared between
channels as follows:
- DMA Channels 0-15 share the 'tx-0-15' interrupt
- DMA Channels 16-31 share the 'tx-16-31' interrupt
- all channels share the 'err' interrupt

Changes in V3:
- Added changelog.

Changes in V2:
- Added new lines in commit description.
- Added "Reviewed-by" tag where received.
- Removed the three commits:
"dmaengine: fsl-edma: move eDMAv2 related registers to a new structure ’edma2_regs’"
"dmaengine: fsl-edma: add eDMAv3 registers to edma_regs"
"dmaengine: fsl-edma: wait until no hardware request is in progress".
I will send a different patchset for them.

Larisa Grigore (5):
  dmaengine: fsl-edma: select of_dma_xlate based on the dmamuxs presence
  dmaengine: fsl-edma: remove FSL_EDMA_DRV_SPLIT_REG check when parsing
    muxbase
  dt-bindings: dma: fsl-edma: add nxp,s32g2-edma compatible string
  dmaengine: fsl-edma: add support for S32G based platforms
  dmaengine: fsl-edma: read/write multiple registers in cyclic
    transactions

[PATCH v3 1/5] dmaengine: fsl-edma: select of_dma_xlate based on the dmamuxs presence

[Larisa Grigore]

Select the of_dma_xlate function based on the dmamuxs definition rather
than the FSL_EDMA_DRV_SPLIT_REG flag, which pertains to the eDMA3
layout.

This change is a prerequisite for the S32G platforms, which integrate both
eDMAv3 and DMAMUX.

Existing platforms with FSL_EDMA_DRV_SPLIT_REG will not be impacted, as
they all have dmamuxs set to zero.

[PATCH v3 2/5] dmaengine: fsl-edma: remove FSL_EDMA_DRV_SPLIT_REG check when parsing muxbase

[Larisa Grigore]

Clean up dead code. dmamuxs is always 0 when FSL_EDMA_DRV_SPLIT_REG set. So
it is redundant to check FSL_EDMA_DRV_SPLIT_REG again in the for loop
because it will never enter for loop.

[PATCH v3 3/5] dt-bindings: dma: fsl-edma: add nxp,s32g2-edma compatible string

[Larisa Grigore]

Introduce the compatible strings 'nxp,s32g2-edma' and 'nxp,s32g3-edma' to
enable the support for the eDMAv3 present on S32G2/S32G3 platforms.

The S32G2/S32G3 eDMA architecture features 32 DMA channels. Each of the
two eDMA instances is integrated with two DMAMUX blocks.

Another particularity of these SoCs is that the interrupts are shared
between channels in the following way:
- DMA Channels 0-15 share the 'tx-0-15' interrupt
- DMA Channels 16-31 share the 'tx-16-31' interrupt
- all channels share the 'err' interrupt
