Hello! These patches add support for the JDI LPM102A188A display panel, found in the Google Pixel C. Patch 1 adds the DT bindings for the panel. Patch 2 adds an optional register clear to the Tegra DSI driver. Patch 3 adds the panel driver, which is based on the downstream kernel driver published by Google and developed by Sean Paul. Patch 4 adds the DT node for the Google Pixel C. There is one point in this series on which I would like to ask for some advice: Since the device's bootloader leaves the display on and in patch 3 I have assumed that the panel must be reset when probing, I was forced to add patch 2, discovered by poking at the DSI module's registers until the panel initialization sequence succeeded. However, if it is okay to keep the panel on from the bootloader then it would be possible to forego this second patch. Any comments on this would be highly appreciated. Thank you!
