Merge branch 'for-linus' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine updates from Vinod Koul: - new drivers for: - Ingenic JZ4780 controller - APM X-Gene controller - Freescale RaidEngine device - Renesas USB Controller - remove device_alloc_chan_resources dummy handlers - sh driver cleanups for peri peri and related emmc and asoc patches as well - fixes and enhancements spread over the drivers * 'for-linus' of git://git.infradead.org/users/vkoul/slave-dma: (59 commits) dmaengine: dw: don't prompt for DW_DMAC_CORE dmaengine: shdmac: avoid unused variable warnings dmaengine: fix platform_no_drv_owner.cocci warnings dmaengine: pch_dma: fix memory leak on failure path in pch_dma_probe() dmaengine: at_xdmac: unlock spin lock before return dmaengine: xgene: devm_ioremap() returns NULL on error dmaengine: xgene: buffer overflow in xgene_dma_init_channels() dmaengine: usb-dmac: Fix dereferencing freed memory 'desc' dmaengine: sa11x0: report slave capabilities to upper layers dmaengine: vdma: Fix compilation warnings dmaengine: fsl_raid: statify fsl_re_chan_probe dmaengine: Driver support for FSL RaidEngine device. dmaengine: xgene_dma_init_ring_mngr() can be static Documentation: dma: Add documentation for the APM X-Gene SoC DMA device DTS binding arm64: dts: Add APM X-Gene SoC DMA device and DMA clock DTS nodes dmaengine: Add support for APM X-Gene SoC DMA engine driver dmaengine: usb-dmac: Add Renesas USB DMA Controller (USB-DMAC) driver dmaengine: renesas,usb-dmac: Add device tree bindings documentation dmaengine: edma: fixed wrongly initialized data parameter to the edma callback dmaengine: ste_dma40: fix implicit conversion ...
