Cover letter [RFC PATCH 0/2] dmaengine: at_hdmac: fix locking according to slave DMA requirements
Hi,
This is an attempt to solve the locking issue that we currently have with the Atmel at_hdmac dmaengine driver.
I tested these patches with several drivers but may need more coverage before making them permanent...
Comments welcome.

interrupts disabled
