From 10b8e0fd3f7234a38db2c8d2c8dec0bd6eeede44 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Fri, 31 May 2024 17:07:10 +0200 Subject: dmaengine: add channel device name to channel registration Channel device name is used for sysfs, but also by dmatest filter function. With dynamic channel registration, channels can be registered after dma controller registration. Users may want to have specific channel names. If name is NULL, the channel name relies on previous implementation, dmachan.
