Subject: [PATCH v4 01/17] drm/bridge: cdns-dsi: Fix the _atomic_check()
Date: Wed, 18 Jun 2025 12:59:04 +0300	[thread overview]
Message-ID: <20250618-cdns-dsi-impro-v4-1-862c841dbe02@ideasonboard.com> (raw)
In-Reply-To: <20250618-cdns-dsi-impro-v4-0-862c841dbe02@ideasonboard.com>

From: Aradhya Bhatia <aradhya.bhatia@linux.dev>

Use the "adjusted_mode" for the dsi configuration check, as that is the
more appropriate display_mode for validation, and later bridge enable.

Also, fix the mode_valid_check parameter from false to true, as the dsi
configuration check is taking place during the check-phase, and the
crtc_* mode values are not expected to be populated yet.

Fixes: a53d987756ea ("drm/bridge: cdns-dsi: Move DSI mode check to _atomic_check()")
