drm/panel: panel-dsi-cm: disable TE for now

2021-04-06T13:51:29+00:00

Disable TE for Droid 4 panel, since implementation is currently broken. Also disable it for N950 panel, which is untested.

drm/panel: kd35t133: allow using non-continuous dsi clock

2021-02-25T09:18:45+00:00

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.

drm/panel: s6e63m0: Support max-brightness

2020-12-30T10:26:08+00:00

The "max-brightness" is a standard backlight property that we need to support for the Samsung GT-I8190 Golden because the display will go black if we crank up the brightness too high. As the platform needs this ability to give picture this is a regression fix along with the addition of the property to the GT-I8190 device tree.

drm/panel: panel-dsi-cm: add panel database to driver

2020-12-15T14:17:31+00:00

Add a panel database to the driver instead of reading propertes from DT data. This is similar to panel-simple, and I believe it's more future safe way to handle the panels.
