4.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dhinakaran Pandiyan <dhinakaran.pandiyan@xxxxxxxxx> commit bdcc02cf1bb508fc700df7662f55058f651f2621 upstream. Entry corresponding to 220 us setup time was missing. I am not aware of any specific bug this fixes, but this could potentially result in enabling PSR on a panel with a higher setup time requirement than supported by the hardware. I verified the value is present in eDP spec versions 1.3, 1.4 and 1.4a.
