2020-04-13soc / drm: mediatek: Fix mediatek-drm device probingEnric Balletbo i Serra1-12/+19
In the actual implementation the same compatible string "mediatek,<chip>-mmsys" is used to bind the clock drivers (drivers/soc/mediatek) as well as to the gpu driver (drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem that the only probed driver is the clock driver and there is no display at all. In any case having the same compatible string for two drivers is not correct and should be fixed. To fix this, and maintain backward compatibility, we can consider that the mmsys driver is the top-level entry point for the multimedia subsystem, so is not a pure clock controller but a system controller, and the drm driver is instantiated by that MMSYS driver.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart3-4/+10
Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <[email protected]> Reviewed-by: Boris Brezillon <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Reviewed-by: Tomi Valkeinen <[email protected]> Tested-by: Sebastian Reichel <[email protected]> Reviewed-by: Sebastian Reichel <[email protected]> Acked-by: Daniel Vetter <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Currently the cursor is placed on the first overlay plane, which means it will be at the bottom of the stack when the hw does the compositing with anything other than primary plane. Since mtk doesn't support plane zpos, change the cursor location to the top-most plane. Signed-off-by: Sean Paul <[email protected]> Signed-off-by: CK Hu <[email protected]>
