2011-10-07video: tegra: provide blank that clears screenJon Mayo
Only clear the display when ioctl FBIOBLANK is FB_BLANK_NORMAL is used This indicates that display should still be powered on and is useful when HDMI audio needs to remain active but no content is displayed on screen. bug 857117 bug 868916 Reviewed-on: http://git-master/r/53608 (cherry picked from commit 234a39002a5a4daa364271ed357de14cff06f6a9) Change-Id: I28b71c693681852933158aa4491a0d164ce64a8f Reviewed-on: http://git-master/r/56443 Tested-by: Jon Mayo <jmayo@nvidia.com> Reviewed-by: Jon Mayo <jmayo@nvidia.com>
2011-08-29video: 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).

If there are more than one hdmi modes that have same xres, yres, and vmode, tegra_dc_hdmi_mode_equal can return true even though pixclocks are way different from each other. Now, tegra_dc_hdmi_mode_equal will retun false if pixclock has more than 1Hz of difference. Also, tegra_fb_set_par will use fb_find_nearest_mode instead of fb_find_best_mode to take refresh rate into the consideration.
