This patch moved the exynos-drm-hdmi platform device registration to the drm driver. When DT is enabled, platform devices needs to be registered within the driver code. This patch fits the requirement of both DT and Non DT based drm drivers.

Is exynos_drm_hdmi_pdev related to exynos_drm_drv? I don't really like such thing. let's comply with layer rule. so how about moving exynos_drm_hdmi_pdev into exynos_drm_hdmi layer and just calling platform_device_hdmi_register instead of platform_device_register_simple? for this, exynos_drm_hdmi_pdev should be defined and declared in exynos_drm_hdmi layer. it means that we have one wrapper to common hdmi layer.

ditto. let's call platform_device_hdmi_unregister instead.

    platform_driver_unregister(&exynos_drm_common_hdmi_driver);
    platform_driver_unregister(&mixer_driver);
    platform_driver_unregister(&hdmi_driver);
