[PATCH v2 03/10] dmaengine: sun6i: Restructure code to allow extension for new SoCs

2017-09-16 Thread Stefan Brüns
The current code mixes three distinct operations when transforming the slave config to register settings: 1. special handling of DMA_SLAVE_BUSWIDTH_UNDEFINED, maxburst == 0 2. range checking 3. conversion of raw to register values As the range checks depend on the specific SoC, move these o
