linux-toradex.git/drivers/dma/imx-dma.c, branch v4.4.27 Linux kernel for Apalis and Colibri modules dmaengine: Add an enum for the dmaengine alignment constraints 2015-08-05T05:23:52+00:00 Maxime Ripard maxime.ripard@free-electrons.com 2015-07-20T08:41:32+00:00 77a68e56aae141d3e9c740a0ac43362af75d4890 Most drivers need to set constraints on the buffer alignment for async tx operations. However, even though it is documented, some drivers either use a defined constant that is not matching what the alignment variable expects (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of power of two. Add a new enum for these alignments that matches what the framework expects, and convert the drivers to it.

Most drivers need to set constraints on the buffer alignment for async tx
operations. However, even though it is documented, some drivers either use

Add a new enum for these alignments that matches what the framework
expects, and convert the drivers to it.

Remove the function is_imx21_dma() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

Split the device_control callback of the Freescale IMX DMA driver to make use
of the newly introduced callbacks, that will eventually be used to retrieve
slave capabilities.
