338 * the "rotation" binding from a device tree node
342 * Looks up the rotation of a panel in the device tree. The orientation of the
343 * panel is expressed as a property name "rotation" in the device tree. The
344 * rotation in the device tree is counter clockwise.
346 * Return: 0 when a valid rotation value (0, 90, 180, or 270) is read or the
347 * rotation property doesn't exist. Return a negative error code on failure.
