[PATCH v2 03/32] media: v4l2-common: Add helper function media_bus_fmt_to_csi2_bpp()
Posted by Frank Li 1 month, 3 weeks ago 
Add helper function media_bus_fmt_to_csi2_bpp() to get media bus fmt's bpp
to reduce codes such as

	static const struct imx7_csi_pixfmt pixel_formats[] = {
        {
                .fourcc = V4L2_PIX_FMT_UYVY,
                .codes  = IMX_BUS_FMTS(
                        MEDIA_BUS_FMT_UYVY8_2X8,
                        MEDIA_BUS_FMT_UYVY8_1X16
                ),
                .yuv    = true,
                .bpp    = 16,
        },
	....

.bpp can be removed from pixel_formats with this helper function.
