The first patch is a preparation patch to ease the review of the second one which actually adds cyclic transfers support. Thanks, Miquèl Changes in v2: * Rebased on top of v6.6-rc1 * Removed the if (!state) superfluous check. * Address a kernel test robot report (unitialized variable in error case) * Simplify the convoluted logic when filling the hardware descriptors Miquel Raynal (2): dmaengine: xilinx: xdma: Prepare the introduction of cyclic transfers dmaengine: xilinx: xdma: Support cyclic transfers drivers/dma/xilinx/xdma-regs.h | 2 + drivers/dma/xilinx/xdma.c | 178 +++++++++++++++++++++++++++++++-- 2 files changed, 172 insertions(+), 8 deletions(-) -- 2.34.1
