2011-11-30video: fbmon: add HDMI dectetion to fbmod edid parsingErik Gilling
Looks for ieee registration number 0x000c03 as per HDMI spec. CEA-861-E section D.6.8. Change-Id: I6875b24c66e8754510edabcb4f9ba682a50d6ac1 Signed-off-by: Erik Gilling <konkers@android.com> Signed-off-by: Lajos Molnar <molnar@ti.com>
2011-11-30video: fbmon: Add support for CEA pixel ratios.Lajos Molnar
CEA defines multiple timings with dual timing ratios that cannot be distinguished from timings parameters. Added 2 new fb flags to specify 4:3 or 16:9 display ratios. Also added a flag that denotes CEA formats that require repeating pixels. Change-Id: I75d413babdcb4048a0ccce6548ed386ad0e52318 Signed-off-by: Lajos Molnar <molnar@ti.com>

2011-11-30Revert "tegra: host: move stale wait checking into the kernel"Rebecca Schultz Zavin
This reverts commit 2d49bf33f3885aab293f12d54447f66e911e3226.
2011-11-30tegra: host: move stale wait checking into the kernelPrajakta Gudadhe
The kernel now receives wait tracking data (similar to gathers and relocs) and compares the current syncpt with the threshold value. If it's old, it gets a kernel mapping and rewrites the method data to use a kernel reserved syncpt that is always 0 (so trivially pops when seen by the HW). Patch has dependency to the user-space patches Submitted on behalf of: Chris Johnson <cjohnson@nvidia.com> original work by: Chris Johnson <cjohnson@nvidia.com> Change-Id: I4d4e5d3b49cab860485c4172f87247f5b4f5ea6e

2011-11-30[ARM] tegra: hdmi nvhdcp driverJon Mayo
Device /dev/nvhdcpX is used to manage NVHDCP on framebuffer /dev/fbX. These devices are created on hdmi driver initialition when it is attached to dc. Currently only one nvhdcp device may be created. An ioctl interface is in video/nvhdcp.h Check for repeaters and store repeater info. userspace application queries this status to authenticate the connection. When authentication fails, auto-renegotiate every 1.75 seconds. Give up after 5 failed attempts, reset after hotplug or policy change. use TEGRA_DC_OUT_NVHDCP_POLICY_ON_DEMAND in tegra_dc_out.flags in board panel configuration to select a different default policy at probe. Currently only TEGRA_DC_OUT_NVHDCP_POLICY_ALWAYS_ON is supported.

2011-11-30video: tegra: host: disable MPE auto-power-gateMayuresh Kulkarni
It is seen that auto-power-gate of MPE causes some issues when long run camera stress test is run. The issue manifest itself in the form of MPE sync-point not getting triggered from hardware and hence the caller who is waiting on it hangs up the system. Disabling auto-power-gate for MPE seems to resolve this issue.
