I think we have to select DRM_KMS_HELPER from DRM_PANEL_EDP.I am encountering this issue on linux-next-20220316 when building 'make qcom_defconfig' on arm32. I selected DRM_KMS_HELPER in DRM_PANEL_EDP and that fails with the following error: Running 'make qcom_defconfig' drivers/gpu/drm/panel/Kconfig:2:error: recursive dependency detected! drivers/gpu/drm/panel/Kconfig:2: symbol DRM_PANEL is selected by DRM_PANEL_BRIDGE drivers/gpu/drm/bridge/Kconfig:8: symbol DRM_PANEL_BRIDGE depends on DRM_KMS_HELPER drivers/gpu/drm/Kconfig:91: symbol DRM_KMS_HELPER is selected by DRM_PANEL_EDP drivers/gpu/drm/panel/Kconfig:102: symbol DRM_PANEL_EDP depends on DRM_PANEL For a resolution refer to Documentation/kbuild/kconfig-language.rst subsection "Kconfig recursive dependency limitations"
The patch for this problem is at https://lore.kernel.org/dri-devel/20220315084559.23510-1-tzimmermann@xxxxxxx/ It's on it's way into upstream. Best regards Thomas
