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. This patch is trying to differentiate platform-specific and bridge driver code by maintaining exynos platform glue code in exynos_drm_dsi.c driver and common bridge driver code in samsung-dsim.c providing that the new platform-specific glue should be supported in the bridge driver, unlike exynos platform drm drivers. - Add samsung_dsim_plat_data for keeping platform-specific attributes like host_ops, irq_ops, and hw_type. - Initialize the plat_data hooks for exynos platform in exynos_drm_dsi.c. - samsung_dsim_probe is the common probe call across exynos_drm_dsi.c and samsung-dsim.c. - plat_data hooks like host_ops and irq_ops are invoked during the respective bridge call chains.
Maybe the Subject should say "Split ... driver" or "Move ... driver" , since it is not adding a new driver here ?
