[ Upstream commit 2d645604f69f3a772d58ead702f9a8e84ab2b342 ]
Various fixes for the Au1200/Au1550/Au1300 DBDMA2 code:
- skip cache invalidation if chip has working coherency circuitry.
- invalidate KSEG0-portion of the (physical) data address.
- force the dma channel doorbell write out to bus immediately with a sync.

I believe author's signoff is missing here.
As the author, I say this patch should not be applied to 4.xx at all. Same for my other 2 MIPS patches.
Thanks for info, where is the threshold, do we need them for 5.10?
Sasha, please drop.
Best regards, Pavel
