2010-10-21[ARM] tegra: Add APB DMA supportColin Cross5-0/+922
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>
2010-10-21[ARM] tegra: Add cpufreq supportColin Cross2-0/+186
Implement cpufreq support for the Tegra SOC. DVFS is handled by the core virtual cpu clock. The frequencies of the two cores are tied together, the highest frequency requested by either core determines the actual frequency. Signed-off-by: Colin Cross <ccross@android.com>
2010-10-21[ARM] tegra: common: Update common clock init tableColin Cross1-2/+2
Renames clocks in the clock init table to match the datasheet names Signed-off-by: Colin Cross <ccross@android.com>
2010-10-21[ARM] tegra: clock: Add dvfs support, bug fixes, and cleanupsColin Cross7-210/+1005
- Add drivers to clock lookup table - Add new pll_m entries - Support I2C U16 divider - Fix rate reporting on 32.768kHz clock - Call propagate rate only if set_rate succeeds - Add support for audio_sync clock - Add 24MHz to PLLA frequency list - Correct i2s1/2/spdifout mux - Add suspend support - Fix enable/disable parent clocks in set_parent - Add max_rate parameter to all clocks - DVFS support - Add virtual cpu clock with dvfs - Support clk_round_rate - Fix requesting very high periph frequencies - Add quirks for PLLU: PLLU is slightly different from the rest of the PLLs. The lock enable bit is at bit 22 instead of 18 in the MISC register, and the post divider field is a single bit with reversed values from other PLLs. - Simplify recalculating clock rates - Fix UART divider flags - Remove unused clock ops Signed-off-by: Colin Cross <ccross@android.com>
2010-10-21[ARM] tegra: Add support for reading fusesColin Cross4-0/+111
The Tegra SOC contains fuses to identify the CPU type and bin, and a unique id. The CPU info is required to determine the correct voltages for each cpu and core frequency. Signed-off-by: Colin Cross <ccross@android.com>
2010-10-21[ARM] tegra: gpio: Add suspend and wake supportColin Cross2-13/+95

2010-10-21[ARM] tegra: pinmux: add safe values, move tegra2, add suspendColin Cross5-396/+603
- 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>
2010-10-21[ARM] tegra: add suspend and mirror irqs to legacy controllerGary King2-0/+139
mirror IRQ enable and disable operations on the legacy PPI system interrupt controller, since the legacy controller is responsible for responding to wakeup interrupts when the CPU is in LP2 idle mode save the irq controller state on suspend and restore on resume Signed-off-by: Gary King <gking@nvidia.com>
2010-10-21[ARM] tegra: Add legacy irq supportColin Cross3-1/+146
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>
2010-10-21[ARM] tegra: update iomapColin Cross3-6/+39
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>
2010-10-20arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre1-2/+0
Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>
2010-10-20arm: return both physical and virtual addresses from addruartJeremy Kerr1-11/+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>.
