media: dt-bindings: media: Define "rotation" property for sensors
Sensors are occasionally mounted upside down to systems such as mobile phones or tablets. In order to use such a sensor without having to turn every image upside down, most camera sensors support reversing the readout order by setting both horizontal and vertical flipping. This patch documents the "rotation" property for camera sensors, mirroring what is defined for displays in Documentation/devicetree/bindings/display/panel/panel.txt .
