This patch set adds the Tegra dc one-shot support. The patch set is tested on Dalmore + Sharp lq101r1sx01. Basically this patch set is just for RFC. Some DRM files are changes, I guess maybe there are better solutions for that. Also, Thierry mentioned that "te-polarity" can be designed as a GPIO since not every display controller has a dedicate TE pin like Tegra. So I will try to create v2 after some comments are received. Please be noticed that the patch #12 is not part of the feature, it's just used for testing.
