    description: |
      An array of maximum supported image sizes in pixels, for details refer to
      Table 2-1 in the S5PV210 SoC User Manual. The meaning of each cell is as
      follows:
       0 - scaler input horizontal size
       1 - input horizontal size for the scaler bypassed
       2 - REAL_WIDTH without input rotation
       3 - REAL_HEIGHT with input rotation

    default: 0x11
    description: |
      A bitmask specifying whether this IP has the input and the output
      rotator. Bits 4 and 0 correspond to input and output rotator
      respectively. If a rotator is present its corresponding bit should be
      set.
