[LF-5.15.32-2.0.0] Add RAW10 support

[khang_letruong]

Dear NXP Team,

I am migrating to the latest BSP release :

In drivers/staging/media/imx/imx8-isi-cap.c :

/*
 * Pixel link input format
 */
struct mxc_isi_fmt mxc_isi_src_formats[] = {
	{
		.name		= "RGB32",
		.fourcc		= V4L2_PIX_FMT_RGB32,
		.depth		= { 32 },
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
	}, {
		.name		= "YUV32 (X-Y-U-V)",
		.fourcc		= V4L2_PIX_FMT_YUV32,
		.depth		= { 32 },
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
+	}, {
+		.name		= "RAWRGB10 (SRGGB10)",
+		.fourcc		= V4L2_PIX_FMT_SRGGB10,
+		.depth		= { 16 },
+		.memplanes	= 1,
+		.colplanes	= 1,
+		.align		= 3,
	}
};

And in drivers/staging/media/imx/imx8-isi-fmt.c

struct mxc_isi_fmt mxc_isi_out_formats[] = {
	{
		.name		= "RGB565",
		.fourcc		= V4L2_PIX_FMT_RGB565,
		.depth		= { 16 },
		.color		= MXC_ISI_OUT_FMT_RGB565,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 3,
		.mbus_code  = MEDIA_BUS_FMT_RGB565_1X16,
	}, {
		.name		= "RGB24",
		.fourcc		= V4L2_PIX_FMT_RGB24,
		.depth		= { 24 },
		.color		= MXC_ISI_OUT_FMT_BGR32P,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
		.mbus_code  = MEDIA_BUS_FMT_RGB888_1X24,

		.depth		= { 24 },
		.color		= MXC_ISI_OUT_FMT_RGB32P,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
		.mbus_code  = MEDIA_BUS_FMT_BGR888_1X24,
	}, {
		.name		= "YUYV-16",
		.fourcc		= V4L2_PIX_FMT_YUYV,
		.depth		= { 16 },
		.color		= MXC_ISI_OUT_FMT_YUV422_1P8P,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 3,
		.mbus_code	= MEDIA_BUS_FMT_YUYV8_1X16,
	}, {
		.name		= "YUV32 (X-Y-U-V)",
		.fourcc		= V4L2_PIX_FMT_YUV32,
		.depth		= { 32 },
		.color		= MXC_ISI_OUT_FMT_YUV444_1P8,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
		.mbus_code	= MEDIA_BUS_FMT_AYUV8_1X32,
	}, {
		.name		= "NV12 (YUYV)",
		.fourcc		= V4L2_PIX_FMT_NV12,
		.depth		= { 8, 8 },
		.color		= MXC_ISI_OUT_FMT_YUV420_2P8P,
		.memplanes	= 2,
		.colplanes	= 2,
		.align		= 4,
		.mbus_code	= MEDIA_BUS_FMT_YUYV8_1X16,
	}, {
		.name		= "YUV444M (Y-U-V)",
		.fourcc		= V4L2_PIX_FMT_YUV444M,
		.depth		= { 8, 8, 8 },
		.color		= MXC_ISI_OUT_FMT_YUV444_3P8P,
		.memplanes	= 3,
		.colplanes	= 3,
		.align		= 4,
		.mbus_code	= MEDIA_BUS_FMT_YUV8_1X24,
	}, {
		.name		= "xBGR32",
		.fourcc		= V4L2_PIX_FMT_XBGR32,
		.depth		= { 32 },
		.color		= MXC_ISI_OUT_FMT_XRGB32,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
		.mbus_code	= MEDIA_BUS_FMT_RGB888_1X24,
	}, {
		.name		= "ABGR32",
		.fourcc		= V4L2_PIX_FMT_ABGR32,
		.depth		= { 32 },
		.color		= MXC_ISI_OUT_FMT_ARGB32,
		.memplanes	= 1,
		.colplanes	= 1,
		.align		= 2,
		.mbus_code	= MEDIA_BUS_FMT_RGB888_1X24,
+	}, {
+		.name		= "RAWRGB10 (SRGGB10)",
+		.fourcc		= V4L2_PIX_FMT_SRGGB10,
+		.depth		= { 16 },
+		.color 		= MXC_ISI_OUT_FMT_RAW16,
+		.memplanes	= 1,
+		.colplanes	= 1,
+		.align		= 3,
+		.mbus_code	= MEDIA_BUS_FMT_SRGGB10_1X10,
	}
};

Compared to previous 5.10 releases, there''s additional .align field. I would like to know what is the suitable value for the RAW10 format as in the code snippet, please ?

Thanks in advance and best regards,
Khang

let me double check this and tell you later

Dear @joanxie ,

Have you had any update on this, please ?

Best Regards,

I don't get reply, but I read the code and found the patch for align is that bsp team a

4l_bound_align_image, then you can find this function is defined in the

https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/v4l2-core/v4l2-common.c?h=lf...

you can focus on the function *w = clamp_align(*w, wmin, wmax, walign),  you can to find how to define the clamp_align then figure out what walign is for

I still don't get any feedback from internal team
