Subject: [PATCH 2/2] drm/rockchip: rk3066_hdmi: Add missing Kconfig selects
Date: Thu, 13 Aug 2026 16:40:19 +0200 [thread overview]
Message-ID: <20260813144019.12089-3-royalnet026@gmail.com> (raw)
In-Reply-To: <20260813144019.12089-1-royalnet026@gmail.com>
rk3066_hdmi.c calls drm_bridge_connector_init(), but
ROCKCHIP_RK3066_HDMI selects neither DRM_BRIDGE_CONNECTOR nor
DRM_DISPLAY_HELPER, whose module carries the bridge-connector code. A
configuration with ROCKCHIP_RK3066_HDMI as the only enabled Rockchip
output option fails to link:
aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/rk3066_hdmi.o: in function `rk3066_hdmi_bind':
rk3066_hdmi.c:(.text+0x7a4): undefined reference to `drm_bridge_connector_init'
aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/rk3066_hdmi.o: in function `rk3066_hdmi_bridge_atomic_enable':
rk3066_hdmi.c:(.text+0xe74): undefined reference to `drm_atomic_helper_connector_hdmi_update_infoframes'
Select both, like ROCKCHIP_CDN_DP, ROCKCHIP_LVDS and ROCKCHIP_RGB do.
DRM_BRIDGE_CONNECTOR in turn selects DRM_DISPLAY_HDMI_STATE_HELPER,
which resolves the second symbol.
Fixes: 57d6811e8a6d ("drm/rockchip: rk3066_hdmi: switch to drm bridge")
