Wei Yongjun	2cbe23f8fc	dmaengine: stm32-dmamux: Remove unnecessary platform_get_resource() error check ... devm_ioremap_resource() already checks if the resource is NULL, so remove the unnecessary platform_get_resource() error check.

Dan Carpenter	4219ff33b2	dmaengine: stm32-dmamux: Fix a NULL vs IS_ERR() check in probe ... devm_ioremap_resource() doesn't return NULL, it returns error pointers.

Pierre-Yves MORDRET	df7e762db5	dmaengine: Add STM32 DMAMUX driver ... This patch implements the STM32 DMAMUX driver. The DMAMUX request multiplexer allows routing a DMA request line between the peripherals and the DMA controllers of the product. The routing function is ensured by a programmable multi-channel DMA request line multiplexer. Each channel selects a unique DMA request line, unconditionally or synchronously with events from its DMAMUX synchronization inputs. The DMAMUX may also be used as a DMA request generator from programmable events on its input trigger signals Signed-off-by: M'boumba Cedric Madianga <cedric.madianga@gmail.com> Signed-off-by: Pierre-Yves MORDRET <pierre-yves.mordret@st.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>	2017-09-27 16:01:35 +05:30
