From d922d58fedcd98ba625e89b625a98e222b090b10 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sat, 6 Feb 2021 14:50:20 +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.
