From: Jai Luthra <j-luthra@xxxxxx> Add support for RGB565, RGB888 and BGR888 media bus formats. The pixel formats for these have a different byte-order than the MIPI bus formats, given the SHIM IP [1] unpacks them into memory as follows: MIPI RGB888 unpacks to: BYTE3 BYTE2 BYTE1 BYTE0 00000000 RRRRRRRR GGGGGGGG BBBBBBBB MIPI RGB565 unpacks to: BIT 15-11 BIT 10-5 BIT 4-0 RRRRR GGGGGG BBBBB [1]: AM62x TRM: 12.6.1.4.5 "CSI_RX_IF Data Memory Organization Details" Link: https://www.ti.com/lit/pdf/spruiv7 Signed-off-by: Jai Luthra <j-luthra@xxxxxx> Signed-off-by: Julien Massot <julien.massot@xxxxxxxxxxxxx> Tested-by: Julien Massot <julien.massot@xxxxxxxxxxxxx> --- .../platform/ti/j721e-csi2rx/j721e-csi2rx.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/drivers/media/platform/ti/j721e-csi2rx/j721e-csi2rx.c b/drivers/media/platform/ti/j721e-csi2rx/j721e-csi2rx.c index 6e58112957ce..15ddc851737a 100644 --- a/drivers/media/platform/ti/j721e-csi2rx/j721e-csi2rx.c +++ b/drivers/media/platform/ti/j721e-csi2rx/j721e-csi2rx.c @@ -188,6 +188,24 @@ static const struct ti_csi2rx_fmt ti_csi2rx_formats[] = { .csi_dt = MIPI_CSI2_DT_RAW10, .bpp = 16, .size = SHIM_DMACNTX_SIZE_16, + }, { + .fourcc = V4L2_PIX_FMT_RGB565X, + .code = MEDIA_BUS_FMT_RGB565_1X16, + .csi_dt = MIPI_CSI2_DT_RGB565, + .bpp = 16, + .size = SHIM_DMACNTX_SIZE_16, + }, { + .fourcc = V4L2_PIX_FMT_XBGR32, + .code = MEDIA_BUS_FMT_RGB888_1X24, + .csi_dt = MIPI_CSI2_DT_RGB888, + .bpp = 32, + .size = SHIM_DMACNTX_SIZE_32, + }, { + .fourcc = V4L2_PIX_FMT_RGBX32, + .code = MEDIA_BUS_FMT_BGR888_1X24, + .csi_dt = MIPI_CSI2_DT_RGB888, + .bpp = 32, + .size = SHIM_DMACNTX_SIZE_32, }, /* More formats can be supported but they are not listed for now. */ -- 2.43.0
