I see the following code which unconditionally registers an SoC-specific
DMA driver in drivers/dma/edma.c:
static int edma_init(void)
{
int ret = platform_driver_register(&edma_driver);
if (ret == 0) {
pdev0 = platform_device_register_full(&edma_dev_info0);
...
}
subsys_initcall(edma_init);
This means that when I boot multi_v7_defconfig on a Tegra system, that
driver probes. Luckily, this doesn't actually seem to cause any visible
symptoms beyond the syslog entry "edma-dma-engine edma-dma-engine.0:
Can't allocate PaRAM dummy slot", but still should be fixed.
