5 daysdrm/panel: himax-hx83102: restore MODE_LPM after sending disable cmdsIcenowy Zheng
When preparing the panel, it seems that it always expects commands to be transferred in LP mode. However, the disable function removes the MIPI_DSI_MODE_LPM flag, and no other function re-adds it. As the unprepare function contains no DSI commands, re-adding the flag just after disabling the panel should be safe. Add the code re-adding the flag after the two commands for disabling the panel are sent. This fixes screen unblanking (after blanking once) on mt8188-geralt-ciri-sku1 device.

2026-03-13drm/panel: novatek-nt36672a: Convert to mipi_dsi_*_multi() helpersChintan Patel
Convert the driver to use the non-deprecated mipi_dsi_*_multi() helpers and mipi_dsi_msleep(). Switch DCS command sequences to the multi context API and accumulate errors via struct mipi_dsi_multi_context. Replace open-coded error handling with the multi helpers and convert nt36672a_send_cmds() and power sequencing accordingly. This patch is intended to functionally be a no-op, though there is one slight change. Previously a failure in regulator_bulk_disable() would have caused nt36672a_panel_unprepare() to return an error. Now it won't. No other errors in nt36672a_panel_unprepare() were propagated, so this makes things consistent.

2026-02-10drm/panel: jdi-lt070me05000: Use MIPI DSI multi functionsChintan Patel
Convert to the non-deprecated mipi_dsi_*_multi() helpers per the TODO list. This reduces boilerplate error checking while providing proper error accumulation. Use mipi_dsi_msleep() and mipi_dsi_usleep_range() macros for delays. Replace mdelay(10) and mdelay(20) with mipi_dsi_usleep_range() calls using tighter slop (10-11ms and 20-21ms respectively) since these functions aren't run often and don't need large timing windows. In jdi_panel_off(), reset the error context between display_off and enter_sleep_mode to preserve the original behavior of continuing power-down even if display_off fails. This ensures enter_sleep_mode executes before GPIO/regulator control, which is critical for proper power sequencing.

2026-02-02drm/panel-edp: Move FriendlyELEC HD702ERobin Murphy
FriendlyELEC's HD702E module is an eDP panel (in as much as it's some LVDS LCD behind a Chrontel CH7511B eDP bridge), so move its data over to the eDP driver, also resolving the warning about the missing bpc value in the process. The unfortunate combination of HPD not being wired up and the RK3399 eDP controller's behaviour seems to result in the EDID not being readable over DP-AUX without probing the panel first, thus the hard-coded mode is still needed to get things going.
