[PATCH 04/11] dmaengine: shdma: remove legacy slave_id parsing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

The slave device is picked through either devicetree or a filter
function, and any remaining out-of-tree drivers would have warned
about this usage since 2015.

Stop interpreting the field finally so it can be removed from
the interface.
