If so, I'm tempted to just kill it (in a > separate patch). I wondered about that too when I first saw that config option. Still, I don't think it's impossible to have a system where the DMA driver isn't useful; looking across a few kernels, I see it being used for: * Audio; I2S and SPDIF, not HD-audio * SPI (master and slave) * The tegra_hsuart driver (not sure what benefit that has over 8250.c...) * This APB/fuse/DMA workaround All of which seem optional given the fourth one isn't required if DMA isn't used. -- nvpublic -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
