For the third change, need request single irq for every channel with the legacy handler. But actually 2 dma channels share one interrupt(16 channel interrupts, but 32 channels.),ch0/ch16,ch1/ch17... For now, just simply request irq without IRQF_SHARED flag, since 16 channels are enough on i.mx7ulp whose M4 domain own some peripherals. change from v1: 1. check .data of 'of_device_id' in probe instead of compatible name. change from v2: 1. move the difference between edma and edma2 into driver data so that no need version checking in fsl-edma.c. change from v3: 1. remove duplicated 'version' and 'dmamux_nr' in 'struct fsl_edma_engine' since they are included in drvdata already. 2. downgrade print log level. 3. address some minor indent issues raised by Vinod.
