This is the wrong attitude. If it were not for a simple oversight
Joonyoung's driver would already be upstream for the past two kernel
releases. So you need to work together to improve that driver to
incorporate what you need.
It sounds like you just need to add an extension for the arch specific
dma api. At first glance this can mimic the approach taken by
Nobuhiro-san with the shdma driver.
