[PATCH 5/6] ARM: OMAP2+: Drop omap_hwmod_dma_info
Tony Lindgren
tony at atomide.com
Tue Aug 29 10:30:00 PDT 2017
We have all of mach-omap2 booting in device tree only
mode now, and this data is populated from device tree.
Note that once we have removed support for the omap legacy
DMA, we can also drop struct omap_dma_dev_attr.
