I vaguely recall that some devices may have had the panel and the backlight hooked up to the same regulator or enable GPIO, so calling panel_set_backlight() too late may cause the DSI panel to malfunction. That said, I'm not familiar with panel_set_backlight(), so perhaps it always only sets the brightness and the power may already be on earlier? Ah... nevermind... I see that panel_enable_backlight() is called prior to panel_set_backlight(), so this looks like it should be fine. Reviewed-by: Thierry Reding <tred...@nvidia.com>
