Make your driver use a platform device or an of_platform device. It's not at all hard.
Here is my first shot.... any other fields that I need to fill in so I
don't have any gotchas?
/* This must exist */
static void warp_device_release(struct device *dev) {}
static struct platform_device warp_device = {
.name = "warp-device",
.id = 0,
.num_resources = 0,
.dev = {
.coherent_dma_mask = ~0ULL,
.release = warp_device_release,
},
};
platform_device_register(&warp_device);
