45 * each display unit. Set up by the caller.
46 * @dev_priv: Pointer to the device private. Set up by the helper.
47 * @unit: The current display unit. Set up by the helper before a call to @clip.
48 * @cmd: The allocated fifo space. Set up by the helper before the first @clip
49 * call.
50 * @num_hits: Number of clip rect commands for this display unit.
51 * Cleared by the helper before the first @clip call. Updated by the @clip
52 * callback.
53 * @fb_x: Clip rect left side in framebuffer coordinates.
54 * @fb_y: Clip rect right side in framebuffer coordinates.
55 * @unit_x1: Clip rect left side in crtc coordinates.

58 * @unit_y2: Clip rect bottom side in crtc coordinates.
59 *
60 * The clip rect coordinates are updated by the helper for each @clip call.
