I asked it several time including in the framework of this thread: https://lore.kernel.org/dmaengine/20220525092306.wuansog6fe2ika3b@mobilestation/ There are dependencies of my patchsets from this one. Please consider dropping it from your dmaengine-next repo while it's still possible since taking DW eDMA and PCie patches through the PCie repo would be more natural. -Sergey > > -Sergey > > > > > -- > > ~Vinod
