    //raw image data to the beginning of next row.
    //
    //Details: The strides are listed as (raw_width, raw_height, stride)
    //triplets. For each supported raw size, there will be a stride associated
    //with it.

    //Property Name: org.codeaurora.qcamera3.opaque_raw.opaque_raw_format
    //
    //Type: byte(enum) [public]
    //  * LEGACY - The legacy raw format where 8, 10, or 12-bit
    //    raw data is packed into a 64-bit word.
    //  * MIPI - raw format matching the data packing described
    //    in MIPI CSI-2 specification. In memory, the data
    //    is constructed by packing sequentially received pixels
    //    into least significant parts of the words first.
    //    Within each pixel, the least significant bits are also
    //    placed towards the least significant part of the word.
    //
    //Details: Lay out of opaque raw data in memory is decided by two factors:
    //         opaque_raw_format and bit depth (implied by whiteLevel). Below
    //         list illustrates their relationship:
    //  LEGACY8:  P7(7:0) P6(7:0) P5(7:0) P4(7:0) P3(7:0) P2(7:0) P1(7:0) P0(7:0)
    //            8 pixels occupy 8 bytes, no padding needed
    //            min_stride = CEILING8(raw_width)
    // LEGACY10:  0000 P5(9:0) P4(9:0) P3(9:0) P2(9:0) P1(9:0) P0(9:0)
    //            6 pixels occupy 8 bytes, 4 bits padding at MSB
    //            min_stride = (raw_width+5)/6 * 8
    // LEGACY12:  0000 P4(11:0) P3(11:0) P2(11:0) P1(11:0) P0(11:0)
    //            5 pixels occupy 8 bytes, 4 bits padding at MSB
    //            min_stride = (raw_width+4)/5 * 8
    //    MIPI8:  P0(7:0)
    //            1 pixel occupy 1 byte
    //            min_stride = raw_width
    //   MIPI10:  P3(1:0) P2(1:0) P1(1:0) P0(1:0) P3(9:2) P2(9:2) P1(9:2) P0(9:2)
    //            4 pixels occupy 5 bytes
    //            min_stride = (raw_width+3)/4 * 5
    //   MIPI12:  P1(3:0) P0(3:0) P1(11:4) P0(11:4)
    //            2 pixels occupy 3 bytes
    //            min_stride = (raw_width+1)/2 * 3
    //Note that opaque_raw_stride needs to be at least the required minimum
    //stride from the table above. ISP hardware may need more generous stride
    //setting. For example, for LEGACY8, the actual stride may be
    //CEILING16(raw_width) due to bus burst length requirement.
