p1022ds_set_monitor_port() is called by the DIU driver when it enables the DIU. This happens on boot, for example, if you enable the framebuffer console. > How does Linux prevent the > NOR flash driver from binding to the device when this mode has been or > will be used? It doesn't. This isn't a simple problem to solve. On the P1022, NOR flash and the DIU are incompatible, and yet that's exactly what we ship on the P1022DS board. We could just remove the NOR flash node from the DTS. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
