Subject: [PATCH] drm/imx: imx-ldb: honor 'native-mode' property when selecting
 video mode from DT
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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
