All Tegra30 ASUS tablets have a similar design pattern in terms of hardware integration of LVDS display panels, like exactly the same GPIOs are used for power and reset, etc. Add a common device-tree for LVDS display panels of Tegra30 ASUS tablets to avoid replicating the boilerplate panel description.
