Please disregard V2. V3 was sent with the changelog added for review.
Best regards,

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

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
upstream: add eDMAv3 support for S32G2/S32G3 SoCs
