From a85f337704f726459ac09c61af8edc9c0d02d585 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Thu, 29 Oct 2020 01:13:49 +0100 Subject: [PATCH 230/351] drm/sun4i: Fix mipi-dsi panel framerate being 2/3 of the expected value This happens on Pinephone and on Pinetab. Both use MIPI-DSI panels. On Pinephone framerate is 36.6 instead of expected 55. On Pinetab the similar 2/3 ratio holds. Myabe there's a bug in BSP and dclk_div should really be 6 instead of 4.
