Hi Sia, Is this patch series available in some public git repo? I want to test it on our HW with DW AXI DMAC. Thanks. --- Eugeniy Paltsev ________________________________________ From: Sia Jee Heng <jee.heng.sia@xxxxxxxxx> Sent: Monday, October 12, 2020 07:21 To: vkoul@xxxxxxxxxx; Eugeniy Paltsev Cc: andriy.shevchenko@xxxxxxxxxxxxxxx; dmaengine@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx Subject: [PATCH 00/15] dmaengine: dw-axi-dmac: support Intel KeemBay AxiDMA The below patch series are to support AxiDMA running on Intel KeemBay SoC. The base driver is dw-axi-dmac but code refactoring is needed, for example: - Support YAML Schemas DT binding. - Replacing Linked List with virtual descriptor management. - Remove unrelated hw desc stuff from dma memory pool. - Manage dma memory pool alloc/destroy based on channel activity. - Support dmaengine device_sync() callback. - Support dmaengine device_config(). - Support dmaegnine device_prep_slave_sg(). - Support dmaengine device_prep_dma_cyclic(). - Support of_dma_controller_register(). - Support burst residue granularity. - Support Intel KeemBay AxiDMA registers. - Support Intel KeemBay AxiDMA device handshake. - Support Intel KeemBay AxiDMA BYTE and HALFWORD device operation. - Add constraint to Max segment size. This patch set is to replace the patch series submitted at: https://urldefense.com/v3/__https://lore.kernel.org/dmaengine/1599213094-30144-1-git-send-email-jee.heng.sia@xxxxxxxxx/__;!!A4F2R9G_pg!Nemc1rSHID2X4d8pr0LNF0nD9Odrn425GRV8MSTPDvPwE6a3iWPeylAJSaxwqXjfPapMO4U$ This patch series are tested on Intel KeemBay platform.
