* [PATCH 1/1] dmaengine: fsl-edma: merge mcf-edma into fsl-edma driver @ 2024-05-09 19:35 Frank Li 2024-05-13 18:12 ` Geert Uytterhoeven 0 siblings, 1 reply; 5+ messages in thread From: Frank Li @ 2024-05-09 19:35 UTC (permalink / raw) To: Vinod Koul, open list:DMA GENERIC OFFLOAD ENGINE SUBSYSTEM, open list, open list:FREESCALE eDMA DRIVER MCF eDMA are almost the same as FSL eDMA driver. Previously link to two kernel modules, fsl-edma.ko and mcf-edma.ko. These are not problem because mcf-edma is for m68k ARCH and FSL eDMA is for arm/arm64 ARCH. But often build both at PPC ARCH. It also makes sense to build two drivers at the same time. It causes many build warning because share a fsl-edma-common.o. such as: powerpc64le-linux-ld: warning: orphan section `.stubs' from `drivers/dma/fsl-edma-common.o' being placed in section `.stubs' powerpc64le-linux-ld: warning: orphan section `.stubs' from `drivers/dma/fsl-edma-trace.o' being placed in section `.stubs' Merge mcf-edma into fsl-edma driver. So use one driver (fsl-edma.ko) for MCF and FSL eDMA. mcf-edma.ko should be replaced by fsl-edma.ko in modules, minimizing user space impact because MCF eDMA remains confined to legacy ColdFire mcf5441x production and mcf5441x has been in production for at least a decade and NXP has long ceased ColdFire development. Update Kconfig to make MCF_EDMA as feature of FSL_EDMA and change Makefile to link mcl-edma-main.o to fsl-edma.o. Create a common module init/exit functions, which call original's fsl-edma-init[exit]() and mcf-edma-init[exit]().

Thanks. I am not sure if recent eDMAv3 and eDMAv5 patch impact mcf5441. eDMAv3 is quite big change. If you can test on mcf5441x, can I send to you a futher clean up for mcf5441x?
