9、为了调试方便，可选修改：

10、先编译一遍tianv2.0的系统，然后增加sunxi-vfe support支持：
rootroot@rootroot-E400:~$ cd wyb/thl_r16_tinav2.0_hm1375/
rootroot@rootroot-E400:~/wyb/thl_r16_tinav2.0_hm1375$

11、加载hm1375的驱动的时候查看I2C是否是通的：
R:\wyb\thl_r16_tinav2.0_hm1375\lichee\linux-3.4\drivers\media\video\sunxi-vfe\device\hm1375.c
static int sensor_detect(struct v4l2_subdev *sd)
{
int ret;
unsigned char rdval;
printk("****wyb %s:%d/%s()! verify HM1375\n", __FILE__, __LINE__, __func__);
LOG_ERR_RET(sensor_read(sd, 0x0001, &rdval))
ret = sensor_read(sd, 0x0001,&rdval);
printk("****wyb %s:%d/%s()! reg:0x0001=value:0xx right=0x03/0x13\n", __FILE__, __LINE__, __func__, rdval);
if (ret < 0) {
vfe_dev_err("sensor_read err at sensor_detect!\n");
return ret;
}
if((rdval != 0x03) && (rdval != 0x13))
{
vfe_dev_err("read high val: %d\n", rdval);
return -ENODEV;
}
LOG_ERR_RET(sensor_read(sd, 0x0002, &rdval))
printk("****wyb %s:%d/%s()! reg:0x0002=value:0xx right=0x75\n", __FILE__, __LINE__, __func__, rdval);
if(rdval != 0x75)
{
vfe_dev_err("read low val: %d\n", rdval);
return -ENODEV;
}
printk("HM1375 sensor_detect OK\r\n");
return 0;
}
（奇怪的时候HM1375的0x0001号寄存器，第一次读是0x03，以后都是0x13，好神奇！）
