Additionally, "2X8" means that one pixel is transferred 22 * in two 8-bit samples, "BE" or "LE" specify in which order those samples are 23 * transferred over the bus: "LE" means that the least significant bits are 24 * transferred first, "BE" means that the most significant bits are transferred 25 * first, and "PADHI" and "PADLO" define which bits - low or high, in the 26 * incomplete high byte, are filled with padding bits. 27 * 28 * The pixel codes are grouped by type, bus_width, bits per component, samples 29 * per pixel and order of subsamples. Numerical values are sorted using generic 30 * numerical sort order (8 thus comes before 10). 31 * 32 * As their value can't change when a new pixel code is inserted in the 33 * enumeration, the pixel codes are explicitly given a numerical value. The next 34 * free values for each category are listed below, update them when inserting 35 * new pixel codes. 36 */ 37 enum v4l2_mbus_pixelcode { 38 V4L2_MBUS_FMT_FIXED = 0x0001, 39 40 /* RGB - next is 0x1009 */ 41 V4L2_MBUS_FMT_RGB444_2X8_PADHI_BE = 0x1001, 42 V4L2_MBUS_FMT_RGB444_2X8_PADHI_LE = 0x1002, 43 V4L2_MBUS_FMT_RGB555_2X8_PADHI_BE = 0x1003, 44 V4L2_MBUS_FMT_RGB555_2X8_PADHI_LE = 0x1004, 45 V4L2_MBUS_FMT_BGR565_2X8_BE = 0x1005, 46 V4L2_MBUS_FMT_BGR565_2X8_LE = 0x1006, 47 V4L2_MBUS_FMT_RGB565_2X8_BE = 0x1007, 48 V4L2_MBUS_FMT_RGB565_2X8_LE = 0x1008, 49 50 /* YUV (including grey) - next is 0x2014 */ 51 V4L2_MBUS_FMT_Y8_1X8 = 0x2001, 52 V4L2_MBUS_FMT_UYVY8_1_5X8 = 0x2002, 53 V4L2_MBUS_FMT_VYUY8_1_5X8 = 0x2003, 54 V4L2_MBUS_FMT_YUYV8_1_5X8 = 0x2004, 55 V4L2_MBUS_FMT_YVYU8_1_5X8 = 0x2005, 56 V4L2_MBUS_FMT_UYVY8_2X8 = 0x2006, 57 V4L2_MBUS_FMT_VYUY8_2X8 = 0x2007, 58 V4L2_MBUS_FMT_YUYV8_2X8 = 0x2008, 59 V4L2_MBUS_FMT_YVYU8_2X8 = 0x2009, 60 V4L2_MBUS_FMT_Y10_1X10 = 0x200a, 61 V4L2_MBUS_FMT_YUYV10_2X10 = 0x200b, 62 V4L2_MBUS_FMT_YVYU10_2X10 = 0x200c, 63 V4L2_MBUS_FMT_Y12_1X12 = 0x2013, 64 V4L2_MBUS_FMT_UYVY8_1X16 = 0x200f, 65 V4L2_MBUS_FMT_VYUY8_1X16 = 0x2010, 66 V4L2_MBUS_FMT_YUYV8_1X16 = 0x2011, 67 V4L2_MBUS_FMT_YVYU8_1X16 = 0x2012, 68 V4L2_MBUS_FMT_YUYV10_1X20 = 0x200d, 69 V4L2_MBUS_FMT_YVYU10_1X20 = 0x200e, 70 71 /* Bayer - next is 0x3015 */ 72 V4L2_MBUS_FMT_SBGGR8_1X8 = 0x3001, 73 V4L2_MBUS_FMT_SGBRG8_1X8 = 0x3013, 74 V4L2_MBUS_FMT_SGRBG8_1X8 = 0x3002, 75 V4L2_MBUS_FMT_SRGGB8_1X8 = 0x3014, 76 V4L2_MBUS_FMT_SBGGR10_DPCM8_1X8 = 0x300b, 77 V4L2_MBUS_FMT_SGBRG10_DPCM8_1X8 = 0x300c, 78 V4L2_MBUS_FMT_SGRBG10_DPCM8_1X8 = 0x3009, 79 V4L2_MBUS_FMT_SRGGB10_DPCM8_1X8 = 0x300d, 80 V4L2_MBUS_FMT_SBGGR10_2X8_PADHI_BE = 0x3003, 81 V4L2_MBUS_FMT_SBGGR10_2X8_PADHI_LE = 0x3004, 82 V4L2_MBUS_FMT_SBGGR10_2X8_PADLO_BE = 0x3005, 83 V4L2_MBUS_FMT_SBGGR10_2X8_PADLO_LE = 0x3006, 84 V4L2_MBUS_FMT_SBGGR10_1X10 = 0x3007, 85 V4L2_MBUS_FMT_SGBRG10_1X10 = 0x300e, 86 V4L2_MBUS_FMT_SGRBG10_1X10 = 0x300a, 87 V4L2_MBUS_FMT_SRGGB10_1X10 = 0x300f, 88 V4L2_MBUS_FMT_SBGGR12_1X12 = 0x3008, 89 V4L2_MBUS_FMT_SGBRG12_1X12 = 0x3010, 90 V4L2_MBUS_FMT_SGRBG12_1X12 = 0x3011, 91 V4L2_MBUS_FMT_SRGGB12_1X12 = 0x3012, 92 93 /* JPEG compressed formats - next is 0x4002 */ 94 V4L2_MBUS_FMT_JPEG_1X8 = 0x4001, 95 }; 96 97 /** 98 * struct v4l2_mbus_framefmt - frame format on the media bus 99 * @width: frame width 100 * @height: frame height 101 * @code: data format code (from enum v4l2_mbus_pixelcode) 102 * @field: used interlacing type (from enum v4l2_field) 103 * @colorspace: colorspace of the data (from enum v4l2_colorspace) 104 */ 105 struct v4l2_mbus_framefmt { 106 __u32 width; 107 __u32 height; 108 __u32 code; 109 __u32 field; 110 __u32 colorspace; 111 __u32 reserved[7]; 112 }; 113 114 #endif 115
