Hi Vinod,
This series contains a single patch that introduces a dedicated dmaengine
bottom-half workqueue along with per-channel BH helpers. The change grew
out of the earlier discussion about moving DMA tasklet usage over to a
BH workqueue and I took some time to get the semantics right
before sending this upstream:
Earlier discussion:

I’m intentionally sending only the foundational helper patch for review
to avoid spamming the list. The full set of driver conversions is already
available here: https://github.com/allenpais/dmaengine-bh-work
Once the base helper patch is reviewed, I will follow up with the
remaining driver conversions.
This series is based on v6.19-rc4 (f10c325a345fef0a688a2bcdfab1540d1c924148).
Thanks,
Allen
