Subject: [PATCH v5 0/9] Enable designware PCI EP EDMA locally
Date: Thu, 10 Mar 2022 13:24:48 -0600	[thread overview]
Message-ID: <20220310192457.3090-1-Frank.Li@nxp.com> (raw)

Default Designware EDMA just probe remotely at host side.
This patch allow EDMA driver can probe at EP side.

1. Clean up patch
   dmaengine: dw-edma: Detach the private data and chip info structures
   dmaengine: dw-edma: remove unused field irq in struct dw_edma_chip
   dmaengine: dw-edma: change rg_region to reg_base in struct
   dmaengine: dw-edma: rename wr(rd)_ch_cnt to ll_wr(rd)_cnt in struct

2. Enhance EDMA driver to allow prode eDMA at EP side
   dmaengine: dw-edma: Add support for chip specific flags   
   dmaengine: dw-edma: Add DW_EDMA_CHIP_32BIT_DBI for chip specific flags

3. Bugs fix at EDMA driver when probe eDMA at EP side
   dmaengine: dw-edma: Fix programming the source & dest addresses for ep
   dmaengine: dw-edma: Don't rely on the deprecated "direction" member

4. change pci-epf-test to use EDMA driver to transfer data.
   PCI: endpoint: functions/pci-epf-test: Support PCI controller DMA

5. Using imx8dxl to do test, but some EP functions still have not
upstream yet. So below patch show how probe eDMA driver at EP
controller driver.
