Upstream series https://lore.kernel.org/linux-media/20250917-csi-bgr-rgb-v3-0-0145571b3aa4@kernel.org/ The subdev format documentation has a subsection describing how to use the media bus pixel codes for serial buses. While it describes the sampling part well, it doesn't really describe the current convention used for the components order. Let's improve that. Signed-off-by: Maxime Ripard <mripard@kernel.org>
Upstream series https://lore.kernel.org/linux-media/20250917-csi-bgr-rgb-v3-0-0145571b3aa4@kernel.org/ The tc358743 is an HDMI to MIPI-CSI2 bridge. It can output all three HDMI 1.4 video formats: RGB 4:4:4, YCbCr 4:2:2, and YCbCr 4:4:4. RGB 4:4:4 is converted to the MIPI-CSI2 RGB888 video format, and listed in the driver as MEDIA_BUS_FMT_RGB888_1X24. Most CSI2 receiver drivers then map MEDIA_BUS_FMT_RGB888_1X24 to V4L2_PIX_FMT_RGB24. However, V4L2_PIX_FMT_RGB24 is defined as having its color components in the R, G and B order, from left to right. MIPI-CSI2 however defines the RGB888 format with blue first. This essentially means that the R and B will be swapped compared to what V4L2_PIX_FMT_RGB24 defines. The proper MBUS format would be BGR888, so let's use that. Fixes: d32d986 ("[media] Driver for Toshiba TC358743 HDMI to CSI-2 bridge") Signed-off-by: Maxime Ripard <mripard@kernel.org>

Tested and does the right thing. I'm happy for this to be merged now, so draft status dropped. |
