From 7b2b34025de4ef1ffde174e55b2aa841dc2c1144 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sat, 6 Feb 2021 14:39:19 +0100 Subject: [PATCH] drm/panel: kd35t133: allow using non-continuous dsi clock The panel is able to work when dsi clock is non-continuous, thus the system power consumption can be reduced using such feature. Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags. Also the flag actually becomes necessary after commit c6d94e37bdbb ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock") and without it the panel only emits stripes instead of output.
