Subject: [PATCH v2 0/6] Add eDMAv3 support for S32G2/S32G3 SoCs

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

Larisa Grigore (6):
  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
