2012-06-20video: tegra: dc: fix MC_DECERR display0_win errors on shutdownAdam Cheney
When a DC window is being released, a NULL flip is used to indicate that the window should be disabled. To disable a window, 0 is written to WIN_OPTIONS. The MC_DECERR on window shutdown is a symptom of forgetting step 2) below when disabling windows, leaving no indication that there is anything to wait for. This causes DC to erroneously unpin the scanout buffer while the buffer is still actively being used. Summary of flip (window update) synchronization in DC: 1) program some window registers 2) set win->dirty=1 3) schedule the activation of the registers 4) request VBLANK or HBLANK interrupts 5) wait for win->dirty==0 In the trigger_windows ISR (every VBLANK or HBLANK): 1) if there is no window update pending in HW, clear dirty flag to indicate that ACTIVE registers are up-to-date. bug 991572 bug 995614 bug 989119 bug 983251 bug 960424 bug 866711 Change-Id: I8b710aac874b202838c3989608b7e0bd15425382 Signed-off-by: Adam Cheney <acheney@nvidia.com> Reviewed-on: http://git-master/r/109370 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Robert Morell <rmorell@nvidia.com> Reviewed-by: Nirav Patel <nipatel@nvidia.com> Reviewed-by: Jon Mayo <jmayo@nvidia.com>

2012-06-18usb: tegra: otg: fix unbalanced suspend/resumeXin Xie
Becasue of a previous workaround, suspend/resume pair is implemented as suspend/complete pair in the driver's dev_pm_ops field. If any driver suspend routine (which is called before otg suspend) failed, then tegra_otg_resume() will be called even tegra_otg_suspend() is not called. This will cause disable the OTG clock, and OTG will not generate any more IRQ. Ideal fix would be use suspend/resume pair to implement the dev_pm_ops, but this might break previous workaround. This patch check suspend() routine is called or not in the resume routine; even we use suspend/ resume pair in the future, it will not cause bad behaviour.

- Deauth frame from p2p GO to client doesn't go from firmware if we do del_virtual_iface immediately. Putting a delay after sending deauth frame to allowed FW to send out deauth frame. - IF_DEL operation was timing out due to wrong status check. Fixed it and added few debug prints. - Sending Provision Discovery directly to GO instead of doing an internal scan. Also put the internal scan count to 3 to have better timings for GO-NEG. - Increase beacon timeout only for concurrent mode. For STA only operation, use the default beacon timeout value (4). - If scan abort is due to timeout, aborting the scan in FW is not required. Moreover, as this scan_timeout call is coming in timer interrupt context, all blocking calls such as fw scan abort will result in kernel panic : don’t call abort in Firmware. - Add p2p_cancel_listen routine.
