 AxiDMA

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.

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@intel.com/__;!!A4F2R9G_pg!Nemc1rSHID2X4d8pr0LNF0nD9Odrn425GRV8MSTPDvPwE6a3iWPeylAJSaxwqXjfPapMO4U$

This patch series are tested on Intel KeemBay platform.
