Subject: [PATCH -next 0/6] dmaengine: xilinx_dma: Add Xilinx AXI MCDMA Engine driver support
Date: Tue, 22 Oct 2019 22:30:16 +0530 [thread overview]
Message-ID: <1571763622-29281-1-git-send-email-radhey.shyam.pandey@xilinx.com> (raw)
This patchset adds Xilinx AXI MCDMA IP support. The AXI MCDMA provides
high-bandwidth direct memory access between memory and AXI4-Stream target
peripherals. It supports up to 16 independent read/write channels.
MCDMA IP supports per channel interrupt output but driver support one
interrupt per channel for simplification. IP specification/programming
sequence and register description is mentioned in PG [1].
The driver is tested with xilinx internal dmatest client. In end usecase
MCDMA will be used by xilinx axiethernet driver using dma API's.
Changes since RFC[2]:
- Remove xilinx axidma multichannel support.
- Addressed all RFC comments except modularizing initialization of channel
segment is skipped as it would create tight coupling b/w axidma and
mcdma internal structures.
- Include MCDMA IP description in Kconfig.
- Few regression fixes from xilinx tree.
NOTE: This patchset is based on next and previous[3] axidma series.
