tina linux怎么把摄像头的接口由mipi改为hispi

jinxiangwzh LV 7

有没有指导文档或者参考例程

转接芯片：安森美MT9J003，然后SoC 编写转接芯片的MIPI程序

jinxiangwzh LV 7

@yuzukitsuru 啥意思还要转接芯片？我现在用的CMOS模组就是MT9J003，这个CMOS是HISPI输出，开发板是用imx317，由imx317切换到MT9J003，我按照Tina Linux Camera
开发指南.pdf 上面说的进行了修改，但是这个上面没有描述修改到HISPI的内容

@jinxiangwzh

HISPI与MIPI完全不是一个接口，怎么可能修改到HISPI，除非芯片支持HISPI接口，不然只能用转接芯片或者FPGA实现一个

jinxiangwzh LV 7

@yuzukitsuru 这位大哥你把我说迷糊了。首先V536支持HiSPi，其次难道你的意思是V536上面MIPI和HiSPi不是共用引脚吗？

柚木鉉 LV 9

@jinxiangwzh 早说是V536，我还以为是V853，sys_config配置为hispi驱动就行了，把mipi-csi-used设置0，找到hispi的used打开就行

jinxiangwzh LV 7

@yuzukitsuru 好，，唉唉。。。让你吓死了

jinxiangwzh LV 7

@yuzukitsuru 没找到你说的，我目前找到的关于hispi的撇脂只有这个

static int sensor_g_mbus_config(struct v4l2_subdev *sd,
                                struct v4l2_mbus_config *cfg)
{
    struct sensor_info *info = to_state(sd);

    cfg->type = V4L2_MBUS_HISPI;
	if (info->isp_wdr_mode == ISP_DOL_WDR_MODE)
		cfg->flags = 0 | V4L2_MBUS_SUBLVDS_4_LANE | V4L2_MBUS_CSI2_CHANNEL_0 | V4L2_MBUS_CSI2_CHANNEL_1;
	else
		cfg->flags = 0 | V4L2_MBUS_SUBLVDS_4_LANE | V4L2_MBUS_CSI2_CHANNEL_0;

    return 0;
}

这里提供的是使用设备树方案的配置名称，对于使用 sys_config.fex 的方案可以对照这里的设备树检查，配置项差别不大。hispi与mipi软件上只需要修改sensor驱动，不需要修改 V4L2框架，更不需要读写寄存器。具体方法参考《Linux_MIPI_CSI_开发指南.pdf》（需要FAE提供）。

这里提供设备树的配置：
