开发板带的s5k4ec没问题，换ov2659失败。
失败kernel 打印：
<3>[ 2.229257] ov2659_back_4(rk_cam_sensor:169): write reg(0x103, val:0x1) failed, try to write again!
<3>[ 2.230601] ov2659_back_4(rk_cam_sensor:169): write reg(0x103, val:0x1) failed, try to write again!

<3>[ 2.232021] ov2659_back_4(rk_cam_sensor:671): soft reset failed
DTS按代码默认的：
ov2659{
is_front = <0>;
rockchip,powerdown = <&gpio3 GPIO_D7 GPIO_ACTIVE_HIGH>;
pwdn_active = <ov2659_PWRDN_ACTIVE>;
#rockchip,power = <>;
pwr_active = <PWR_ACTIVE_HIGH>;
#rockchip,reset = <>;
#rst_active = <>;
#rockchip,flash = <>;
#rockchip,af = <>;
mir = <0>;
flash_attach = <0>;
resolution = <ov2659_FULL_RESOLUTION>;
powerup_sequence = <ov2659_PWRSEQ>;
orientation = <0>;
i2c_add = <ov2659_I2C_ADDR>;
i2c_rata = <100000>;
i2c_chl = <0>;
cif_chl = <0>;
mclk_rate = <24>;
};
