When using MMIO with regmap, fast_io is implied. No need to set it
again.

drm/bridge: dw-hdmi-qp: Use common HDMI output bus fmts helper

2026-06-09T20:03:51+00:00

Make use of the common drm_bridge_funcs.atomic_get_output_bus_fmts
helper for HDMI bridge connectors.

This allows dw-hdmi-qp HDMI bridges to participate in recursive bus
format selection in a meaningful way.

drm/bridge: synopsys: dw-dp: Support unregistering the AUX channel

2026-06-02T19:27:59+00:00

The DisplayPort AUX channel gets initialized and registered during
dw_dp_bind(), but it is never unregistered, which may lead to resource
leaks and/or use-after-free.

Add the missing dw_dp_unbind() function to allow the users of the
library to handle the required cleanup, i.e. unregister the AUX adapter.

drm/bridge: dw-hdmi-qp: Use the common TMDS char rate constant

2026-05-21T09:45:52+00:00

Replace the driver local HDMI14_MAX_TMDSCLK define with the shared
constant defined in the  header.

The local define incorrectly referenced HDMI 1.4, but the 340 MHz
maximum TMDS character rate was actually introduced in HDMI 1.3.
