V851S DVP DTS/.fex 设置

[kanken6174]

大家好，在我的基于 V851S 的主板上通过 MIPI-CSI 成功使用 GC2053 后，我尝试使用 OV5640（应该受支持，因为它有驱动程序）来验证 DVP 端口是否正常工作。

现在我的问题是 DVP 的文档非常混乱。 他们似乎暗示现在应该通过相应地修改 DTS 来设置 DVP，而不是旧的 .fex 格式。 问题在于，与 .fex 相比，DTS 缺少一些定义，例如如何指定 MLCK 引脚？ PLCK 怎么样？ 目前我的配置不会产生任何结果，因为 MLCK 引脚 (NCSI_MLCK) 似乎没有为相机提供时钟。

这是我当前的 DTS (如您所见，旧的 GC2053 定义现已禁用以避免出现问题)：

			sensor0:sensor@0 {
				device_type = "sensor0";
				sensor0_mname = "gc2053_mipi";
				sensor0_twi_cci_id = <1>;
				sensor0_twi_addr = <0x6e>;
				sensor0_mclk_id = <0>;
				sensor0_pos = "rear";
				sensor0_isp_used = <1>;
				sensor0_fmt = <1>;
				sensor0_stby_mode = <0>;
				sensor0_vflip = <1>;
				sensor0_hflip = <0>;
				sensor0_iovdd-supply = <>;
				sensor0_iovdd_vol = <1800000>;
				sensor0_avdd-supply = <>;
				sensor0_avdd_vol = <2800000>;
				sensor0_dvdd-supply = <>;
				sensor0_dvdd_vol = <1200000>;

				sensor0_reset = <&pio PA 8 1 0 1 0>;
				sensor0_pwdn = <&pio PA 9 1 0 1 0>;
				/*sensor0_sm_hs = <&pio PE 2 1 0 1 0>;*/
				/*sensor0_sm_vs = <&pio PE 3 1 0 1 0>;*/
				flash_handle = <&flash0>;
				act_handle = <&actuator0>;
				status	= "disabled";
			};
			sensor1:sensor@1 {
				device_type = "sensor1";
				sensor1_mname = "ov5640";
				sensor1_twi_cci_id = <2>;
				sensor1_twi_addr = <0x78>;
				sensor1_mclk_id = <1>;
				sensor1_pos = "front";
				sensor1_isp_used = <1>;
				sensor1_fmt = <1>;
				sensor1_stby_mode = <0>;
				sensor1_vflip = <0>;
				sensor1_hflip = <0>;
				sensor1_iovdd-supply = <>;
				sensor1_iovdd_vol = <1800000>;
				sensor1_avdd-supply = <>;
				sensor1_avdd_vol = <2800000>;
				sensor1_dvdd-supply = <>;
				sensor1_dvdd_vol = <1200000>;
				sensor1_power_en = <>;
				sensor1_reset = <&pio PD 8 1 0 1 0>;
				sensor1_pwdn = <>;
				sensor1_sm_hs = <&pio PE 2 1 0 1 0>;
				sensor1_sm_vs = <&pio PE 3 1 0 1 0>;
				flash_handle = <>;
				act_handle = <>;
				status	= "okay";
			};

这是我的引脚设置：

谁能确认我是否需要使用 DTS 或 .fex 才能使其正常工作？ 如果是这样，我如何指定 NCSI_MLCK 和 PLCK 引脚?
