    Subject[RFC PATCH 3/8] drm/panel: nv3052c: Sleep for 150ms after reset
    Date
    The current code waits after resets for 5 to 20 milliseconds.
    This is appropriate when resetting a sleeping panel, but an awake panel
    requires at least 120ms of waiting.

    Sleep for 150ms so the panel always completes it reset properly.
