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
