| | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - the reset values for some pin groups in the tegra pin mux can result in functional errors due to conflicting with actively-configured pin groups muxing from the same controller. this change adds a known safe, non- conflicting mux for every pin group, which can be used on platforms where the pin group is not routed to any peripheral - also add each pin group's I/O voltage rail, to enable platform code to map from the pin groups used by each interface to the regulators used for dynamic voltage control - add routines to individually configure the tristate, pin mux and pull- ups for a pingroup_config array, so that it is possible to program individual values at run-time without modifying other values. this allows driver power-management code to reprogram individual interfaces into lower power states during idle / suspend, or to reprogram the pin mux to support multiple physical busses per internal controller (e.g., sharing a single I2C or SPI controller across multiple pin groups) - move chip-specific data like pingroups and drive-pingroups out of the common code and into chip-specific code - fix debug output for group with no pullups - add a TEGRA_MUX_SAFE function. Setting a pingroup to TEGRA_MUX_SAFE will automatically select a mux setting that is guaranteed not to conflict with any of the hardware blocks. Signed-off-by: Gary King <gking@nvidia.com>

| | | | | | | | The "legacy irq controller" duplicates the functionality of the GIC, but remains powered during the cpu suspend and idle modes that power down the CPU and the GIC. Signed-off-by: Colin Cross <ccross@android.com>
* [ARM] tegra: update iomapColin Cross2010-10-212-6/+33
| | | | | | | | Add missing io address map entries from datasheet. Add the IRAM area to the statically mapped io regions. Correct the onewire, USB, and statmon addresses Signed-off-by: Colin Cross <ccross@android.com>
* arm: return both physical and virtual addresses from addruartJeremy Kerr2010-10-201-11/+15
| | | | | | | | | | | | | | | | | | | | Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in. Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com> and Tony Lindgren <tony@atomide.com>, and fix for versatile express from Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.
