drm/msm: Fix return type of mdp4_lvds_connector_mode_valid

2022-09-30T16:57:53Z

The mode_valid field in drm_connector_helper_funcs is expected to be of type: enum drm_mode_status (* mode_valid) (struct drm_connector *connector, struct drm_display_mode *mode); The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of mdp4_lvds_connector_mode_valid should be changed from int to enum drm_mode_status.

drm/msm/mdp4: get rid of struct mdp4_platform_config

2022-07-04T18:05:31Z

Struct mdp4_platform_config is a relict from the DT-conversion time. Move the max_clk field to the mdp4_kms_init(), the place where it is used and drop the struct mdp4_platform_config and the mdp4_get_config() function.

drm/msm/mdp4: move iommu_domain_alloc() call close to its usage

2022-07-04T18:05:31Z

Move iommu_domain_alloc() in front of adress space/IOMMU initialization. This allows us to drop it from struct mdp4_cfg_platform which remained from the pre-DT days.

drm: Drop drm_framebuffer.h from drm_crtc.h

2022-06-20T20:53:55Z

drm_crtc.h has no need for drm_frambuffer.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_framebuffer.h. Quite a few placs do currently depend on drm_framebuffer.h without actually including it directly. All of those need to be fixed up. v2: Fix up msm some more v2: Deal with ingenic and shmobile as well Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220614095449.29311-1-ville.syrjala@linux.intel.com Acked-by: Sam Ravnborg Acked-by: Jani Nikula

2022-06-18T16:14:05Z

of_graph_get_remote_node() returns remote device node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.

drm/msm: make mdp5/dpu devices master components

2022-04-25T21:50:46Z

The msm_mdss serves several roles at this moment. It provides IRQ domain used by MDP5 and DPU drivers but it also serves as a component master for both those usecases. MDP4 (which does not have separate MDSS device) is the component master on it's own. Remove this assymmetry and make both MDP5 and DPU component masters too. This removes a need to care about drm/components from msm_mdss driver, removes an mdss pointer from struct msm_drm_private and simplifies the interface between mdp5/dpu and msm_drv.
