2011-12-15tegra: fb: HDMI monitor spec. not correct via "mode" device.Andre Sihera
When monitor is auto-detected on HDMI port, a special structure is initialised to hold the video mode properties for the plugged- in monitor. From this the display string is generated for displa via the "mode" character device under /sys. When the monitor is disconnected, the structures associated with the monitor tself are cleared, but the pointer to the video mode properties structure was left initialised and so pointed into thin air, which resulted in garbage appearing on the "mode" device. Added explicit deinitialisation code to reset pointer to video mode properties so "cat mode" within /sys yields an empty string when the HDMI monitor is unplugged.

2011-11-30video: tegra: dc: Separate allocations for U and VRobert Morell
Currently, dc_ext only takes a single nvmap memory ID per overlay, even in the YUV case (the U and V planes are expected to be differentiated using an offset from the beginning of the nvmap allocation). This is problematic for some software flows, such as certain video interlacing algorithms that will vary the luma plane while keeping the chrome plane constant. This change allows dc_ext clients to specify a different nvmap allocation for each of the Y, U, and V planes. If a YUV surface is used and no U or V plane allocation is specified, the old behavior is preserved: the U and V offsets are assumed to be within the same allocation as Y. Note: this changes the behavior of the offset parameter: the old code added offset to offset_u and offset_v when using it. The new code treats all three offsets as relative to the beginning of the allocation. It also fixes a bug in the code where offset was applied twice to the Y plane. I believe this is safe because the presence of this bug means that no existing clients are using offset != 0 (or if they are, they're already broken).
