Cover letter [PATCH RFC 00/26] Migrate more OMAP DMA code to DMA engine
Quoted 11 lines · Russell King - ARM Linux
The following patch series moves code to setup the DMA hardware and service interrupts from the hardware to the DMA engine driver. This reduces the dependency on the legacy DMA implementation.
This series does not remove the channel allocation/freeing hooks which are used to manage the allocation of physical channels - this is the next step in the evolution.
The patches which move the interrupt handling are currently less than perfect since they're writing to
ENABLE_L0under a different spinlock, and hence RFC only at the moment.
Nice to see this happening. These seem to work for me based on a quick try on omap2+, but on omap1 the build fails:
arch/arm/mach-omap1/dma.c: In function ?dma_write?:arch/arm/mach-omap1/dma.c:186: error: ?const struct omap_dma_reg? has no member named ?size?
