[PATCH v2 21/27] drm/rockchip: dw_hdmi_qp: Add QMS support

From: Nicolas Frattaroli

Date: Thu Nov 05 2026 - 11:31:15 EST


Add the "Media" VRR display mode to the set of VRR display modes being
registered, and set the qms_supported flag in the connector's HDMI
sub-struct. The actual QMS functionality itself is implemented in the
common HDMI state helpers.
