标题: 请教HDMI TX输出配置
我使用的是evm3588开发板。

在函数dw_hdmi_attach_properties里默认显示格式是MEDIA_BUS_FMT_YUV8_1X24，HDMI显示输出正常。
u64 color = MEDIA_BUS_FMT_YUV8_1X24;

即在函数dw_hdmi_attach_properties中
查询代码对应输出格式为：
            hdmi->hdmi_output = RK_IF_FORMAT_YCBCR444;
            hdmi->colordepth = 8;

现在修改为MEDIA_BUS_FMT_UYVY10_1X20

即在函数dw_hdmi_attach_properties中
u64 color = MEDIA_BUS_FMT_UYVY10_1X20;

即在函数dw_hdmi_attach_properties中查询代码对应输出格式为：
            hdmi->hdmi_output = RK_IF_FORMAT_YCBCR422;
            hdmi->colordepth = 10;

测试结果，HDMI匹配出错，不断的打印：

请教一下，怎么才能把8bit YUV444 输出模式修改为10 bitYUV422
