| * ARM: tegra: remove Seaboard board filesStephen Warren2012-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Seaboard device tree supports all the features that the Seaboard board files support. Hence, there's no need to keep the board files around any more; all users should convert to device tree. MACH_KAEN and MACH_WARIO are also removed. While tegra-seaboard.dts doesn't support those explicitly, it would be trivial to create device trees for those boards if anyone cares. The Seaboard device tree is now compiled if Tegra2 support is enabled, rather than when Seaboard support is enabled. Signed-off-by: Stephen Warren <swarren@nvidia.com>
| * ARM: tegra: remove CONFIG_MACH_TEGRA_DTStephen Warren2012-06-20
| | | | | | | | | | | | | | | | | | | | | | * Make ARCH_TEGRA select USE_OF; DT is the way forward. * Build board-dt-tegra*.c when the relevant Tegra SoC support is enabled, rather than requiring a specific config option for this. * The board-specific config options already build board-*-pinmux.o, and when booting from device tree these files are no longer needed, so we can remove some Makefile commands related to those files.

| * | ARM: tegra: use APB DMA for accessing APB devicesOlof Johansson2012-02-06

The workaround is to use apb dma to read/write the registers instead. There is a dependency loop between fuses, clocks, and APBDMA. If dma is enabled, fuse reads must go through APBDMA to avoid corruption due to a hw bug. APBDMA requires a clock to be enabled. Clocks must read a fuse to determine allowable cpu frequencies. Separate out the fuse DMA initialization, and allow the fuse read and write functions to be called without using DMA before the DMA initialization has been completed. Access to the fuses before APBDMA is initialized won't hit the hardware bug because nothing else can be using DMA. Original fuse registar access code from Varun Wadekar <vwadekar@nvidia.com>, improved by Colin Cross <ccross@android.com> and later moved to separate driver by Jon Mayo <jmayo@nvidia.com>.

Devices will be added to this file as more drivers are added that can make use of them. This is based on work contributed by several people, most of it from Colin Cross and Erik Gilling.

* | ARM: tegra: Add external memory controller driverColin Cross2011-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | The frequency memory bus on Tegra can be adjusted without disabling accesses to memory by updating the memory configuration registers from a per-board table, and then changing the clock frequency. The clock controller and memory controller have an interlock that prevents the new memory registers from taking effect until the clock frequency change.

* [ARM] tegra: Add APB DMA supportColin Cross2010-10-21
| | | | | | | | | | | | | | | | | 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 <konkers@android.com> Signed-off-by: Colin Cross <ccross@android.com>
