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 (8):
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
dmaengine: fsl-edma: move eDMAv2 related registers to a new structure
’edma2_regs’
dmaengine: fsl-edma: add eDMAv3 registers to edma_regs
dt-bindings: dma: fsl-edma: add nxp,s32g2-edma compatible string
dmaengine: fsl-edma: add support for S32G based platforms
dmaengine: fsl-edma: wait until no hardware request is in progress
dmaengine: fsl-edma: read/write multiple registers in cyclic
transactions
