From: Robin Gong
Date: Thu Jul 02 2020 - 02:53:43 EST
This patchset enable fsl-edma3 which is used on i.mx8qxp/i.mx8qm. There
are big changes on fsl-edma so that add indepent fsl-edma3 here:
1. split memory address for per channel, while all channels share the same
memory address and the same control registers CR/INT..etc.
2. all TCD registers of channels are continuous on legacy edma but split on
edma3.
3. per interrupt per channel on edma3.
4. totally different register layer and add some register such as SBR
5. power domain support, per domain per channel.
The first 4 patches are used for preparing no any function changes involed.
