drm/bridge: analogix_dp: Split bind() into probe() and real bind()

2020-04-09T08:29:35+00:00

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 ...

drm/rockchip: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:05:53+00:00

It's (almost, there's some iommu stuff without significance) right above the drm_dev_put(). This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). Aside: Another driver with a bit much devm_kzalloc, which should probably use drmm_kzalloc instead ... v2: Explain why this cleanup is possible (Laurent). v3: Jump out at the right label (Francesco) v4: Try again, kbuild caught that I didn't build test this properly ... v5: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Acked-by: Sam Ravnborg Cc: Sam Ravnborg Cc: Thomas Zimmermann Cc: Francesco Lavra Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Sandy Huang Cc: "Heiko Stübner" Cc: linux-arm-kernel@lists.infradead.org Cc: linux-rockchip@lists.infradead.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-38-daniel.vetter@ffwll.ch

drm/rockchip: rgb: don't count non-existent devices when determining subdrivers

2020-03-11T08:44:14+00:00

rockchip_drm_endpoint_is_subdriver() may also return error codes. For example if the target-node is in the disabled state, so no platform-device is getting created for it. In that case current code would count that as external rgb device, which in turn would make probing the rockchip-drm device fail. So only count the target as rgb device if the function actually returns 0.

drm: Remove drm_fb_helper add, add all and remove connector calls

drm_fb_helper_{add,remove}_one_connector() and drm_fb_helper_single_add_all_connectors() are dummy functions now and serve no purpose. Hence remove their calls. This is the preparatory step for removing the drm_fb_helper_{add,remove}_one_connector() functions from drm_fb_helper.h This removal is done using below sementic patch and unused variable compilation warnings are fixed manually. @@ @@ - drm_fb_helper_single_add_all_connectors(...); @@ expression e1; statement S; @@ - e1 = drm_fb_helper_single_add_all_connectors(...); - S @@ @@ - drm_fb_helper_add_one_connector(...); @@ @@ - drm_fb_helper_remove_one_connector(...); Changes since v1: * Squashed warning fixes into the patch that introduced the warnings (into 5/7) (Laurent, Emil, Lyude) Signed-off-by: Pankaj Bharadiya Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Reviewed-by: Alex Deucher Reviewed-by: Lyude Paul Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20200305120434.111091-6-pankaj.laxminarayan.bharadiya@intel.com
