+ This patch set add new version of edma for i.mx7ulp, the main changes
are as belows:
- 1. only one dmamux.
- 2. another clock dma_clk except dmamux clk.
- 3. 16 independent interrupts instead of only one interrupt for

+ 3. 16 independent interrupts instead of only one interrupt for
+ all channels.
+ For the first change, need modify fsl-edma-common.c and mcf-edma,
so create the first two patches to prepare without any function impact.

+ 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.
+ 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.
-
-change from v4:
- 1. correct typo.
