Subject: [PATCH v6 3/7] drm/display: Add soft depend for aux-hpd-typec-dp-bridge module
Date: Tue,  4 Aug 2026 15:07:26 +0800	[thread overview]
Message-ID: <20260804070730.68-4-kernel@airkyi.com> (raw)
In-Reply-To: <20260804070730.68-1-kernel@airkyi.com>

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

The aux-hpd-typec-dp-bridge module serves as a generic TypeC
DisplayPort HPD bridge and is not required by any other
module. Therefore, it will not be auto-loaded.

Given that the drm_display_helper module houses DisplayPort-related
helper code, add a MODULE_SOFTDEP() within it to suggest loading the
aux-hpd-typec-dp-bridge module beforehand.
