Hack to prevent boot lock-up if HDMI is not connected. This has been observed on recent T20 SoC production lots produced some when after mid 2015. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Dominik Sliwa <dominik.sliwa@toradex.com>
2014-04-29arm: tegra: dc: disable dc when framebuffer off detectedStefan Agner
Don't initialize the whole display controller (dc) when framebuffer mode is set to off. This avoids creation of the /dev/tegra_dc_x device. The tegra X driver requires for each tegra_dc_x device an framebuffer device with the same id. This patch avoids creation of both, which makes the tegra X driver load correctly. Note: Turning off tegrafb0 still leads to kernel crash due to hard coded device enumeration.

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>
