Subject: [PATCH v3] usb: typec: altmodes: select DRM_AUX_HPD_BRIDGE for TYPEC_DP_ALTMODE
Date: Thu, 9 Jul 2026 14:21:47 +0800 [thread overview]
Message-ID: <20260709062147.240-1-kernel@airkyi.com> (raw)
From: Chaoyi Chen <chaoyi.chen@rock-chips.com>
When TYPEC_DP_ALTMODE is enabled, DRM_AUX_HPD_BRIDGE is most likely
also needed for embedded platforms. Select it when available.
