DMA_CSELR missing for L4 #1001
Comments

I've added the defines at least, but pulling out all the functionality for this channel selection system, for both f0/l4 and anyone else who uses it is bigger than I'm doing personally. Thanks for the pointer though! |

Far from complete support for the channel selection systems on f0/l4, but at least brings in the defines needed for doing this yourself. Fixes libopencm3#1001

The data sheet shows DMA1_CSELR and DMA2_CSELR to select which peripheral uses which dma on page 297 and tables 41 and 42. Currently no defines are available for l4 (only for f0 in f0/dma.h). Also no functions to set the register values.
