Before updating modes on HDMI hotplug, check if framebuffer is registered at all. This allows to disable framebuffers completely.
2013-11-26hdmi: avoid division by zero oopsStefan Agner
After suspend, mode filter might be called with empty yres. This leads to division by zero when checking aspect ratio. Return as invalid mode when yres is zero.

2011-11-30video: tegra: Implement EDID queryRobert Morell
This change implements the TEGRA_DC_EXT_CONTROL_GET_OUTPUT_EDID ioctl in the dc_ext interface. It first adds a way for the tegra dc EDID module to export EDID data safely, without the risk of reading an incomplete or corrupted EDID in the presence of hotplug, by moving the actual data to a substructure with a lifetime maintained by a kref. Then, that support is plumbed through the hdmi block (which is currently the only way to get at the EDID) and out to userspace.

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.
