Subject: [PATCH v2 2/5] drm/bridge: cdns-mhdp8546: Use drm_dp_enhanced_frame_cap()
Date: Thu, 29 Oct 2026 11:18:23 +0100 [thread overview]
Message-ID: <20261029101826.72773-3-dmitrymalovanyy@gmail.com> (raw)
In-Reply-To: <20261029101826.72773-1-dmitrymalovanyy@gmail.com>
Use the helper instead of checking DP_ENHANCED_FRAME_CAP directly, so
enhanced framing is used for all DPCD r1.2+ sinks as the spec requires.
Compile tested only.
