drm/imx: imx-ldb: honor 'native-mode' property when selecting video mode from DT
This patch allows to select a specific video mode from a list of modes defined in DT by setting the 'native-mode' property appropriately. This change does not affect the behaviour of existing platforms, since they either: - have just one display-timings subnode - have the native-mode property pointing to the first entry - let the bootloader select the appropriate timing Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
