2010-05-07fsl udc: Fix cable connect/disconnect checkingtegra-9.12.11Venkat Moganty
On VBUS interrupt irq acknowledges the VBUS interrupt and schedules the work thread for powering/up down the USB phy and clocks based on the VBUS status. But, in the work thread instead of checking the VBUS status directly, rechecking the interrupt status which is already disabled. This is fixed by checking the vbus status only in the work thread for controlling the power up/down sequence. Due to the disconnect problem power numbers increased when there is no USB cable connected to the system.

2010-04-28tegra harmony: remove the WAR added to turn on disaply after resumeMayuresh Kulkarni
When this code was written, we were not aware of how to turn on harmony's display using a single key press. Also, after resume if none of the wake-locks is acquired then system immediately goes to suspend. To avoid this, we added this WAR to acquire a timed wake lock of 10 sec. This gives the user a chance to either press a key/insert-remove usb cable/insert-remove SD card after which the display turns on. Now that we have the way to turn on display by any press, this WAR is not needed. Tested on android + harmony (A02, R04 EC firmware) for LP0 and LP1.

The CPU clock was previously boosted to 300 MHz for USB device on cable connect for performance optimization. Following issues were noted with this setting: 1. it is above low limit (250MHz) used to turn off slave CPU. Hence it will never be turned off when cable is connected. 2. it is also above PLLP 216MHz output. Hence high power PLLX will be kept alive. Reducing the CPU boost frequency to 200 MHz to address the above issues with minimal impact on the performance. Bug 654486: [whistler/android] - Large difference in USB MSD perf with DFS OFF.

2010-04-21tegra RM: Upadted CPU clock control in LP2 state.Alex Frid
Upadted CPU clock control in LP2 state: - Disabled PLLX on entry to LP2 - Forced CPU divider 1:1 setting on entry to LP2, and restore divider on exit (speed up LP2 entry/exit) - Removed PLLC and PLLM from wake source consideration (commonly these PLLs are disabled in LP2 anyway, but using them in rare case when they are available may create dangerous over-clocking condition) Change-Id: Ied51ebee553766e66d6007e1149270e243df0543 Reviewed-on: http://git-master/r/1155 Tested-by: Aleksandr Frid <afrid@nvidia.com> Reviewed-by: Narendra Damahe <ndamahe@nvidia.com> Reviewed-by: Gary King <gking@nvidia.com>
