This patch series (v2: http://www.spinics.net/lists/dmaengine/msg08274.html) contains a number of mostly minor fixes and cleanups for the DW DMA driver. A couple of them affect the DT binding so these may need to be updated to maintain compatibility. The rest should be relatively straight-forward. This version has been tested on the following bare metal platforms: - ATNGW100 (avr32 based platform) with MMC - Sam460ex (powerpc 44x based platform) with SATA - Intel Braswell with UART - Intel Galileo (Intel Quark based platform) with UART (SATA driver and Intel Galileo UART support are based on this series and not available in upstream yet) Vinod, there are few patch sets developed on top of this one, so, the idea is to keep this in an immuutable branch / tag. Changes since v2: - add patch 1 to fix master selection which was broken for long time - remove "use field-by-field initialization" patch since like Mans metioned in has mostly no value and even might increase error prone - rebase on top of recent linux-next - wide testing on several platforms Changes since v1: - zeroing struct dw_dma_slave before use - fall back to old data_width property if data-width is not found - append tags for few patches - correct title of cover letter - rebase on top of recent linux-next Andy Shevchenko (11): dmaengine: dw: fix master selection dmaengine: dw: rename masters to reflect actual topology dmaengine: dw: substitute dma_read_byaddr by dma_readl_native dmaengine: dw: revisit data_width property dmaengine: dw: define counter variables as unsigned int dmaengine: dw: keep entire platform data in struct dw_dma dmaengine: dw: pass platform data via struct dw_dma_chip dmaengine: dw: move dwc->paused to dwc->flags dmaengine: dw: move dwc->initialized to dwc->flags dmaengine: dw: move residue to a descriptor dmaengine: dw: set cdesc to NULL when free cyclic transfers Mans Rullgard (4): dmaengine: dw: set src and dst master select according to xfer direction dmaengine: dw: fix byte order of hw descriptor fields dmaengine: dw: set LMS field in descriptors dmaengine: dw: clear LLP_[SD]_EN bits in last descriptor of a chain Documentation/devicetree/bindings/dma/snps-dma.txt | 9 +- arch/arc/boot/dts/abilis_tb10x.dtsi | 2 +- arch/arm/boot/dts/spear13xx.dtsi | 4 +- arch/avr32/mach-at32ap/at32ap700x.c | 16 +- drivers/ata/sata_dwc_460ex.c | 6 +- drivers/dma/dw/core.c | 355 ++++++++++----------- drivers/dma/dw/pci.c | 5 +- drivers/dma/dw/platform.c | 27 +- drivers/dma/dw/regs.h | 55 ++-- drivers/spi/spi-pxa2xx-pci.c | 8 +- drivers/tty/serial/8250/8250_pci.c | 8 +- include/linux/dma/dw.h | 5 +- include/linux/platform_data/dma-dw.h | 15 +- sound/soc/intel/common/sst-firmware.c | 2 +- 14 files changed, 268 insertions(+), 249 deletions(-) -- 2.7.0 -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
