I renew my will of helping in any kind of manner in this, I love the
intention for EDMAv2 to have an upstream driver instead of SSDK, hoping
in the future to also have the same treatement for EDMAv1 (it's really a
pitty to have a support hole with ipq807x not supported)

Feel free to send an email or anything, considering this is massive, an
extra eye before sending might make things better than reaching (I can
already see this) a massive series with at least 20 revision given the
complexity of this thing.
