136  * direction_for_rotation() - Get the correct reading direction for a given rotation
140  * This function will use the @rotation setting of a source plane to compute the reading
152 	 * The CRTC writing direction is from A to B. The plane reading direction  in direction_for_rotation()
154 	 * The reading direction is computed by rotating the vector AB (top-left to top-right) in a  in direction_for_rotation()
183  * @direction: direction of the reading
185  * @src_line: source line of the reading. Only the top-left coordinate is used. This rectangle
188  * @src_x_start: x start coordinate for the line reading
189  * @src_y_start: y start coordinate for the line reading
193  * This function is mainly a safety net to avoid reading outside the source buffer. As the
