Well, there are two "DMA" drivers. The one in drivers/dma binds on fsl,eloplus-dma, and then manually scans for children with the "fsl,eloplus-dma-channel" compatible. This driver works today because the fsl,eloplus-dma nodes are children of the SOC node, which is already probed. The other is in sound/soc/fsl and binds on "fsl,ssi-dma-channel". These are also children of the fsl,eloplus-dma node. This driver does NOT work today, because the fsl,eloplus-dma is not probed. I do not want the two drivers to depend on each other. They are completely separate. So I don't want to call of_platform_populate() from the drivers/dma driver. I could call it from the sound/soc/fsl driver, however. I will try to see if that works. They only problem I see with this is that I am thinking about modifying the drivers/dma driver to probe on "fsl,eloplus-dma-channel" channels directly. If I do that, then who should call of_platform_populate()? -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
