From 4de3a8fa334851e642d4889d6afa6e5d3daea10a Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Mon, 5 Apr 2010 13:16:42 -0700 Subject: [ARM] tegra: Add APB DMA support The APB DMA block handles DMA transfers to and from some peripherals in the Tegra SOC. It reads from sequential addresses on the memory bus, and writes repeatedly to the same address on the APB bus. Two transfer modes are supported, oneshot for transferring a known size to or from a peripheral, and continuous for streaming data. In continuous mode, a callback occurs when the buffer is half full to allow the existing data to be handled and a new request queued.x v2 changes: dma API no longer uses PTR_ERR Signed-off-by: Erik Gilling Signed-off-by: Colin Cross --- arch/arm/mach-tegra/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arm/mach-tegra/Makefile') diff --git a/arch/arm/mach-tegra/Makefile b/arch/arm/mach-tegra/Makefile index 2a3762179ccf..fc069a9e0f6b 100644 --- a/arch/arm/mach-tegra/Makefile +++ b/arch/arm/mach-tegra/Makefile @@ -12,6 +12,7 @@ obj-$(CONFIG_ARCH_TEGRA_2x_SOC) += tegra2_dvfs.o obj-$(CONFIG_ARCH_TEGRA_2x_SOC) += pinmux-t2-tables.o obj-$(CONFIG_SMP) += platsmp.o localtimer.o headsmp.o obj-$(CONFIG_HOTPLUG_CPU) += hotplug.o +obj-$(CONFIG_TEGRA_SYSTEM_DMA) += dma.o obj-$(CONFIG_CPU_FREQ) += cpu-tegra.o obj-${CONFIG_MACH_HARMONY} += board-harmony.o -- cgit v1.2.3
