Hi,
with this series the edma two driver setup will be changed to have only one
driver to support eDMA3. The legacy edma interface will be removed and eDMA can
only be used via dmaengine API from this point on.
In order to do the merge the following improvements has been done:
- One driver instance per eDMA:
- Any number of eDMA instances are supported (both legacy and DT boot)
- Not relying on global variables, arrays, etc
- Code simplification and optimizations in several places
This change will also help us to do bigger changes in the eDMA driver since,
since now we have only one driver to work with.
The series has been tested on:
da850-evm (OMAP-L138)
- with legacy and DT boot (both eDMA0 and eDMA1 is enabled)
- In code swapping the eDMA instances in legacy mode to make sure the second
instance is handled correctly.
am335x-evmsk
- DT boot
I think this series could go via the dmaengine tree. Changes are trivial under
arch/arm/
Regards,
Peter
