From bdcc02cf1bb508fc700df7662f55058f651f2621 Mon Sep 17 00:00:00 2001 From: Dhinakaran Pandiyan Date: Fri, 11 May 2018 12:51:42 -0700 Subject: drm/psr: Fix missed entry in PSR setup time table. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

This change adds a somewhat hacky check in dm_update_crtcs_state that will update the stream if old and newunderscan values are different. This was causing 4k on Fiji to allow underscan when it wasn't permitted.
