[PATCH 10/14] dmaengine: ti: omap-dma: Pass sdma auxdata to driver and use it
From: Tony Lindgren <tony@atomide.com>
Date: 2019-12-17 00:20:02
Also in:
dmaengine, linux-devicetree, linux-omap
Subsystem:
arm port, dma generic offload engine subsystem, omap2+ support, texas instruments dma drivers, the rest · Maintainers:
Russell King, Vinod Koul, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Vignesh Raghavendra, Linus Torvalds
We can now start passing sdma auxdata to the dmaengine driver to start removing the platform based sdma init.
