* | ARM: tegra: fix compilation error due to mach/hardware.h removalMarc Dietrich2011-10-101-1/+0
|/ | | | | | | | | | | This fixes a compilation error in cpu-tegra.c which was introduced in dc8d966bccde ("ARM: convert PCI defines to variables") which removed the now obsolete mach/hardware.h from the mach-tegra subtree.

* ARM: tegra: cpufreq: Adjust memory frequency with cpu frequencyColin Cross2011-02-211-0/+21
| | | | | | | | | | Adjusts the minimum memory frequency when the cpu frequency changes. The values are currently hardcoded to a reasonable default. If memory frequency scaling is not enabled this patch will have no effect. Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Colin Cross <ccross@android.com>
* ARM: tegra: cpufreq: Take an extra reference to pllxColin Cross2011-02-211-0/+2
| | | | | | | | | | During cpu frequency changes, take an extra reference to pllx so that it doesn't turn off and on while the cpu is temporarily on pllp. If the cpu is moved to pllp permanently, pllx will be turned off. Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Colin Cross <ccross@android.com>
* ARM: tegra: clock: Drop CPU dvfsColin Cross2011-02-211-1/+1
| | | | | | | | | The existing version did not extend well to core dvfs, drop it for now until the new clk api with clk_prepare and clk_unprepare is ready and non-atomic clocks are possible. Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Colin Cross <ccross@android.com>
* ARM: tegra: cpufreq: Disable cpufreq during suspendColin Cross2011-02-111-15/+60
| | | | | | | | | | | | | | | | On Tegra, calling clk_set_rate on the CPU clock may call into the regulator API. If the regulator driver that controls the CPU voltage rail has been suspended, this can lead to attempted communication with a hardware block that has already been turned off. Adds a SUSPEND_PREPARE notification hook to drop the frequency to the lowest possible during suspend. Also adds 216MHz (off of PLLP) as the lowest CPU frequency, which allows PLLX to be turned off.

* [ARM] tegra: Add cpufreq supportColin Cross2010-10-221-0/+185
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>
