2014-12-18video: tegra: fb: fix pixel clock polarityMarcel Ziswiler
The pixel clock polarity setting was wrong: The kernel display flags are rather somewhat confusing: The flags specify the edge where the data should be driven by the controller (and hence not sampled by the display!). Please note that we don't change the default pixel clock polarity.

When grepping through sysfs, grep tries to read all sysfs files which are available. Some of them lead to error due to null pointers. Therefor check for null pointers before using them.

2013-09-09apalis/colibri_t30: fix HDMI hang issueMax Krummenacher
Initialisation of the framebuffer console on DVI-D aka HDMI always failed on monitors which report the vertical front porch to be 1 in their EDID. The fix now changes also the modedb and not only the list of videomodes with a compatible timing. This was particularly bad on Apalis T30 where this is activated by default. On Colibri T30 this was observed when enabling it using the fbcon=map:1 boot argument.

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.

Add support to set a global gamma correction table via fbdev cmap API. The 3 Tegra DC windows have their own local gamma tables, which can either override or alter the global table.

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).
