I have it working now but I had to apply the patch [1] provided by Tomi in order for it to work properly Can you send another revision with his patch included in the series? With that, you can add Tested-by: Adam Ford <aford173@xxxxxxxxx> #imx8mp-beacon-kit Thank you. adam [1] - https://gitlab.com/ideasonboard/nxp/linux/-/commit/d6477fe673b1c0d05d12ae21d8db9a03b07e7fea > > thanks > > adam > > > > > diff --git a/drivers/media/platform/rockchip/rkisp1/rkisp1-capture.c b/drivers/media/platform/rockchip/rkisp1/rkisp1-capture.c > > index a352893308b6..b50b044d22af 100644 > > --- a/drivers/media/platform/rockchip/rkisp1/rkisp1-capture.c > > +++ b/drivers/media/platform/rockchip/rkisp1/rkisp1-capture.c > > @@ -97,6 +97,12 @@ static const struct rkisp1_capture_fmt_cfg rkisp1_mp_fmts[] = { > > .uv_swap = 0, > > .write_format = RKISP1_MI_CTRL_MP_WRITE_YUVINT, > > .mbus = MEDIA_BUS_FMT_YUYV8_2X8, > > + }, { > > + .fourcc = V4L2_PIX_FMT_UYVY, > > + .uv_swap = 0, > > + .yc_swap = 1, > > + .write_format = RKISP1_MI_CTRL_MP_WRITE_YUVINT, > > + .mbus = MEDIA_BUS_FMT_YUYV8_2X8, > > }, { > > .fourcc = V4L2_PIX_FMT_YUV422P, > > .uv_swap = 0, > > @@ -231,6 +237,13 @@ static const struct rkisp1_capture_fmt_cfg rkisp1_sp_fmts[] = { > > .write_format = RKISP1_MI_CTRL_SP_WRITE_INT, > > .output_format = RKISP1_MI_CTRL_SP_OUTPUT_YUV422, > > .mbus = MEDIA_BUS_FMT_YUYV8_2X8, > > + }, { > > + .fourcc = V4L2_PIX_FMT_UYVY, > > + .uv_swap = 0, > > + .yc_swap = 1, > > + .write_format = RKISP1_MI_CTRL_SP_WRITE_INT, > > + .output_format = RKISP1_MI_CTRL_SP_OUTPUT_YUV422, > > + .mbus = MEDIA_BUS_FMT_YUYV8_2X8, > > }, { > > .fourcc = V4L2_PIX_FMT_YUV422P, > > .uv_swap = 0, > > @@ -464,6 +477,20 @@ static void rkisp1_mp_config(struct rkisp1_capture *cap) > > rkisp1_write(rkisp1, RKISP1_CIF_MI_XTD_FORMAT_CTRL, reg); > > } > > > > + /* > > + * U/V swapping with the MI_XTD_FORMAT_CTRL register only works for > > + * NV12/NV21 and NV16/NV61, so instead use byte swap to support UYVY. > > + * YVYU and VYUY cannot be supported with this method. > > + */ > > + if (rkisp1->info->features & RKISP1_FEATURE_MI_OUTPUT_ALIGN) { > > + reg = rkisp1_read(rkisp1, RKISP1_CIF_MI_OUTPUT_ALIGN_FORMAT); > > + if (cap->pix.cfg->yc_swap) > > + reg |= RKISP1_CIF_OUTPUT_ALIGN_FORMAT_MP_BYTE_SWAP_BYTES; > > + else > > + reg &= ~RKISP1_CIF_OUTPUT_ALIGN_FORMAT_MP_BYTE_SWAP_BYTES; > > + rkisp1_write(rkisp1, RKISP1_CIF_MI_OUTPUT_ALIGN_FORMAT, reg); > > + } > > + > > rkisp1_mi_config_ctrl(cap); > > > > reg = rkisp1_read(rkisp1, RKISP1_CIF_MI_CTRL); > > @@ -507,6 +534,20 @@ static void rkisp1_sp_config(struct rkisp1_capture *cap) > > rkisp1_write(rkisp1, RKISP1_CIF_MI_XTD_FORMAT_CTRL, reg); > > } > > > > + /* > > + * U/V swapping with the MI_XTD_FORMAT_CTRL register only works for > > + * NV12/NV21 and NV16/NV61, so instead use byte swap to support UYVY. > > + * YVYU and VYUY cannot be supported with this method. > > + */ > > + if (rkisp1->info->features & RKISP1_FEATURE_MI_OUTPUT_ALIGN) { > > + reg = rkisp1_read(rkisp1, RKISP1_CIF_MI_OUTPUT_ALIGN_FORMAT); > > + if (cap->pix.cfg->yc_swap) > > + reg |= RKISP1_CIF_OUTPUT_ALIGN_FORMAT_SP_BYTE_SWAP_BYTES; > > + else > > + reg &= ~RKISP1_CIF_OUTPUT_ALIGN_FORMAT_SP_BYTE_SWAP_BYTES; > > + rkisp1_write(rkisp1, RKISP1_CIF_MI_OUTPUT_ALIGN_FORMAT, reg); > > + } > > + > > rkisp1_mi_config_ctrl(cap); > > > > mi_ctrl = rkisp1_read(rkisp1, RKISP1_CIF_MI_CTRL); > > -- > > 2.39.2 > >
