DSI one shot support requires register access in the tegra framebuffer to poke the frame trigger bit (with both the trigger bit and the tearing effect signal are high, a frame of pixels will be sent to the panel). The boot args must also be expanded to have a "use tearing effect" flag.

2010-05-17tegra mmc: enable MMC_UNSAFE_RESUME config for tegra_harmony_androidDeepesh Gujarathi
Normally, when the system goes into suspend, all the storage cards are removed and later re-enumerated upon resume. During re-enumeration the device name and number are not guaranteed to be the same as they were during bootup. This can cause data corruption on cards. When the MMC_UNSAFE_RESUME config is enabled, it will prevent kernel from unmounting the mmc cards before suspend. Upon resume the cards will still be using the same device id as they were before suspend. This change seems to fix a lot of mmc related issues that occur during LP0 transitions. partial fix for Bug 679959 Change-Id: Ib90f95ebbc81c5b6e9e83e740ece31f914a262eb Reviewed-on: http://git-master/r/1412 Reviewed-by: Narendra Damahe <ndamahe@nvidia.com> Tested-by: Narendra Damahe <ndamahe@nvidia.com> Reviewed-by: Gary King <gking@nvidia.com>

2010-05-07udc/tegra: configure memory prefetcher for USBPavan Kunapuli
When we are programming two DTDs very close to each other, the second DTD is being prefetched before it is actually written to DDR. To prevent this, we disable prefetcher before programming any new DTD and re-enable it before priming endpoint.

Also use l2 cache code only if it is enabled via config. This is useful when running with l2 cache disabled. Tested on Harmony + Android for LP0 with l2 cache enabled.

2010-05-07tegra ALSA: Replacing completion object with wait_queue_head_tSandeep Shinde
Following are the changes done: - Removed completion object appl_ptr_comp used for waiting for app buffers when buffer_in_quque=0. - If a completion object wakes-up after every 120 seconds if not signalled during that time. - Now using wait_queue_head_t which suits the purpose better. - Removed play_thread running dependency on shutdown_thrd as it is no more required. - Removed label EXIT from play_thread All these changes were done based on comments from Google. Refer to below issues for the complete discussion. http://codereview.chromium.org/1705013/show Change-Id: Id902a73f704ddf38ec8b9071bc36ee0f6db89f30 Reviewed-on: http://git-master/r/1305 Reviewed-by: Manjula Gupta <magupta@nvidia.com> Tested-by: Manjula Gupta <magupta@nvidia.com> Reviewed-by: Gary King <gking@nvidia.com>
2010-05-07tegra_uvc:graceful exit when usb camera is unpluggedSachin Nikam
Bug 657105 Problem:When the USB Camera is unplugged while preview VIDIOC_DQBUF ioctl hangs in uvc_queue_waiton() as it waits on interrupt which will never come, as USB Camera is unplugged. Solution:Using wait_event_interruptible_timeout() instead of wait_event_interruptible() in function uvc_queue_waiton() with timeout value 250 mSec so as to gracefully exit. With this change VIDIOC_DQBUF ioctl returns error, USB Camera driver handles this error to gracefully exit.

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.
