This patch adds device tree bindings for Himax HX8369A DRM panel driver.
Signed-off-by: Liu Ying Ying.Liu@freescale.com --- v8->v9: * Rebase onto the imx-drm/next branch of Philipp Zabel's open git repository.
v7->v8: * None.
v6->v7: * None.
v5->v6: * None.
v4->v5: * Merge the bs[3:0]-gpios properties into one property - bs-gpios. This addresses Andrzej Hajda's comment.
v3->v4: * Newly introduced in v4. This is separated from the relevant driver patch in v3 to address Stefan Wahren's comment.
