2011-06-29cpufreq interactive governor: Update target frequency calculationAlex Frid
Updated target frequency calculation algorithm to take into account current rate CPU is running at: - When CPU is running below go_maxspeed_load threshold, adjust the target frequency based on current rate to reach tunable sustainable load (instead of applying cpu load to max possible cpu rate). Tuned by setting new node ("0" falls back to using max_rate): /sys/devices/system/cpu/cpufreq/interactive/sustain_load - When CPU is running at/above go_maxspeed_load threshold, ramp the target frequency starting from current exponentially with tunable base (instead of immediate jump to maximum cpu rate). Tuned by setting new node ("0" falls back to jump to max_rate): /sys/devices/system/cpu/cpufreq/interactive/boost_factor Defaults for the new tunning parameters are set to "0" - so no changes in governor default behavior.

Revert MMC_BLOCK_DEFERRED_RESUME feature from SD driver. The feature was not implemented thread-safe. Fixing it would require a lot of locking logic at limited value. Deferred resume has no effect on eMMC, because eMMC will be used right after resume. For SD card it only saves power between resume and first SD card access, which is a limited usecase. It does not save power on normal SD card idle.

2011-06-15HID: magicmouse: Don't report REL_{X,Y} for Magic TrackpadChase Douglas
With the recent switch to having the hid layer handle standard axis initialization, the Magic Trackpad now reports relative axes. This would be fine in the normal mode, but the driver puts the device in multitouch mode where no relative events are generated. Also, userspace software depends on accurate axis information for device type detection. Thus, ignoring the relative axes from the Magic Trackpad is best.

2011-06-14nvhost: Add checks for # of GPU register sets.Terje Bergstrom
Checks from a fuse whether we have one or two register sets. - fuse.h/fuse.c: Implement tegra_register_sets() - nvhost_3dctx.c: Use tegra_register_sets() to determine number of sets to save. - dev.c: Create entry /sys/module/nvhost/parameters/register_sets to return to user space the number of sets.

2011-06-14Revert "usb: fsl_udc: tegra: Fix for reducing turnaround errors."Alex Frid
This reverts commit 141f664e2b5052d7fcd57c5287ae1e27db0f658b. The original commit (a) renamed con_id for shared user clock from "sclk" to "hclk" (b) increased requested clock rate Since there is no "hclk" shared bus in tegra clock tree, this effectively disabled busy hint from USB driver, and actually reduced the bus clock (instead of increasing it). Bug 821986 sated that clock effect has not been tested. Reverting it would at least restore 80MHz bus clock limit required for USB operations.

In error path vddio rail is reset to NULL to prevent above problem.
