Document 'data-active' property in R-Car VIN device tree bindings.
Signed-off-by: Jacopo Mondi <jacopo+renesas@xxxxxxxxxx>
v1 -> v2:
- HSYNC is used in place of data enable signal only when running with
explicit synchronizations.
- The property is no more mandatory when running with embedded
synchronizations, and default is selected.
