drm/bridge: implement generic DP HPD bridge

Several USB-C controllers implement a pretty simple DRM bridge which implements just the HPD notification operations. Add special helper for creating such simple bridges.

drm/bridge: add transparent bridge helper

2023-12-04T14:07:29+00:00

Define a helper for creating simple transparent bridges which serve the only purpose of linking devices into the bridge chain up to the last bridge representing the connector. This is especially useful for DP/USB-C bridge chains, which can span across several devices, but do not require any additional functionality from the intermediate bridges.

drm: bridge: Generalize Exynos-DSI driver into a Samsung DSIM bridge

2023-03-28T00:05:41+00:00

Samsung MIPI DSIM controller is common DSI IP that can be used in various SoCs like Exynos, i.MX8M Mini/Nano. In order to access this DSI controller between various platform SoCs, the ideal way to incorporate this in the drm stack is via the drm bridge driver. We already have a consolidated code for supporting component and bridge based DRM drivers, so keep the exynos component based code in existing exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c Tested-by: Marek Szyprowski Reviewed-by: Marek Vasut Signed-off-by: Marek Szyprowski Signed-off-by: Jagan Teki Signed-off-by: Inki Dae
