Marek Szyprowski 04da88c86c drm/bridge: analogix_dp: Split bind() into probe() and real bind() ... [ Upstream commit 83a196773b ] Analogix_dp driver acquires all its resources in the ->bind() callback, what is a bit against the component driver based approach, where the driver initialization is split into a probe(), where all resources are gathered, and a bind(), where all objects are created and a compound driver is initialized. Extract all the resource related operations to analogix_dp_probe() and analogix_dp_remove(), then call them before/after registration of the device components from the main Exynos DP and Rockchip DP drivers. Also move the plat_data initialization to the probe() to make it available for the analogix_dp_probe() function. This fixes the multiple calls to the bind() of the DRM compound driver when the DP PHY driver is not yet loaded/probed: [drm] Exynos DRM: using 14400000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 14400000.fimd (ops fimd_component_ops [exynosdrm]) exynos-drm exynos-drm: bound 14450000.mixer (ops mixer_component_ops [exynosdrm]) exynos-dp 145b0000.dp-controller: no DP phy configured exynos-drm exynos-drm: failed to bind 145b0000.dp-controller (ops exynos_dp_ops [exynosdrm]): -517 exynos-drm exynos-drm: master bind failed: -517 ...
