X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ffedc7ade784610549592baef51895d96e747b7a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/psr: Fix missed entry in PSR setup time table. 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.
