Patch 1 adds the DT bindings for the panel. Patch 2 adds a register clear to the Tegra DSI driver, needed for the panel initialization commands to be properly sent. 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. The first version of this patch series can be found at: https://lore.kernel.org/all/20220929170502.1034040-1-diogo.ivo@tecnico.ulisboa.pt/ Changes in v2: - Patch 1: remove touchscreen reset gpio property - Patch 2: clear register based on its value rather than a DT property - Patch 3: tune backlight delay values - Patch 4: add generic node names, remove underscores Thank you.
