大家好，我是第一次接触RK平台，现需要在RK3288平台上使用MIPI接口的OV5695 camera，在7.1的代码中在“hardware/rockchip/camera/SiliconImage/isi/drv/”中找到了ov5695的driver，但是在配置cam_board_rk3288.xml时遇到了问题，我们power使用的与公版不一样，AVDD 2.8V使用的是PMUGPIO0_C1_d， DOVDD 1.8V使用的是VCC18_DVP
，DVDD 1.2V使用的是PMUGPIO0_B6_d，请问这种情况在cam_board_rk3288.xml中还是添NC吗？
另外除了hardware文件夹下的内容还需要在kernel中修改吗，请各位大神帮忙解惑。
有个porting 文档，，，看看群文件
RK平台MIPI camera应该不需要改到DTS文件吧，我现在只是修改了XML文件，menuconfig或者defconfig之类的文件还需要修改吗？ 以下是我改的xml

VDD 1.2V使用的是PMUGPIO0_B6_d，按照下面的格式配置dts设正确的吗？
isp: isp@ff910000 {
compatible = "rockchip,rk3288-isp", "rockchip,isp";
...............
rockchip,gpios = <&gpio0 GPIO_B6 GPIO_ACTIVE_HIGH>;
rockchip,isp,iommu_enable = <1>;
iommus = <&isp_mmu>;
status = "disabled";
};
以下是Kernel log，从log里看是request gpio fail，什么情况会出现request gpio fail

DTS文件中的status要添什么是okay还是disabled，现在的情况是request gpio都是fail
