Here are clean up and big refactoring against Synopsys DesignWare DMA driver. Some fixes are related to Intel iDMA 32-bit type of controller which has been tested on Intel Merrifield platform. The big refactoring splits out specific DW and iDMA 32-bit parts for better maintenance. Changelog v3: - rebase on top of v5.0-rc1 - drop Fixes tag from patch 1, it's simple an enhancement (Vinod) - use proper format for SPDX for header files (Vinod) - add Greg KH's ACK Changelog v2: - rebase on top of topic/dw branch of dmaengine subsystem - append few more patches, especially one that removes is_private property - fix code kbuild bot complains about - fix some typos which slipped during refactoring and haven't been noticed during test Andy Shevchenko (7): dmaengine: dw: Add missed multi-block support for iDMA 32-bit dmaengine: dw: Remove misleading is_private property dmaengine: dw: Remove unused internal property dmaengine: dw: Split DW and iDMA 32-bit operations dmaengine: dw: Reset DRAIN bit when resume the channel dmaengine: dw: Don't pollute CTL_LO on iDMA 32-bit dmaengine: dw: convert to SPDX identifiers .../devicetree/bindings/dma/snps-dma.txt | 2 - drivers/dma/dw/Kconfig | 2 + drivers/dma/dw/Makefile | 2 +- drivers/dma/dw/core.c | 244 ++++-------------- drivers/dma/dw/dw.c | 138 ++++++++++ drivers/dma/dw/idma32.c | 160 ++++++++++++ drivers/dma/dw/internal.h | 15 +- drivers/dma/dw/pci.c | 53 ++-- drivers/dma/dw/platform.c | 22 +- drivers/dma/dw/regs.h | 30 ++- drivers/tty/serial/8250/8250_lpss.c | 1 - include/linux/dma/dw.h | 9 +- include/linux/platform_data/dma-dw.h | 12 +- 13 files changed, 425 insertions(+), 265 deletions(-) create mode 100644 drivers/dma/dw/dw.c create mode 100644 drivers/dma/dw/idma32.c -- 2.19.2
