dt-bindings: exynos_dsim: update of graph bindings
Of-graph bindings should describe ports present in the device, not the devices it can be connected to. The patch replaces verbose description with shorter but more precise one. While at it clock related properties are moved to the main node as it is their actual location. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
