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

drm/bridge: imx: Add i.MX8qm/qxp pixel combiner support

2022-06-20T19:15:07+00:00

This patch adds a drm bridge driver for i.MX8qm/qxp pixel combiner. The pixel combiner takes two output streams from a single display controller and manipulates the two streams to support a number of modes(bypass, pixel combine, YUV444 to YUV422, split_RGB) configured as either one screen, two screens, or virtual screens. The pixel combiner is also responsible for generating some of the control signals for the pixel link output channel. For now, the driver only supports the bypass mode.
