Following setup here: TinkerBoard-S with rk3288 Chip running armbian with legacy Kernel 4.4.199
Now I would like to add an overlay to the existing one. Here is how the existing one looks like:
dsi@ff960000 {

rockchip,grf = <0x47>;
ports {
#address-cells = <0x1>;
#size-cells = <0x0>;
port {

phandle = <0xea>;
#size-cells = <0x0>;
endpoint@0 {

};
};
mipi-panel {

};

};
};
};

aliases {
i2c0 = "/i2c@ff650000";
i2c1 = "/i2c@ff140000";
i2c2 = "/i2c@ff660000";
i2c3 = "/i2c@ff150000";

Now I would like to attach a different panel to dsi0. Therefore I have created and compiled the following overlay:
/dts-v1/;
/plugin/;

compatible = "rockchip,rk3288-miniarm", "rockchip,rk3288";
fragment@0 {

//dsi,flags = <(MIPI_DSI_MODE_VIDEO | MIPI_DSI_MODE_VIDEO_BURST)>;
//dsi,format = <MIPI_DSI_FMT_RGB888>;
//bus-format = <MEDIA_BUS_FMT_RGB666_1X18>;
dsi,lanes = <2> ;
status = "okay";
panel-init-sequence = [
05 20 01 29
05 96 01 11
];
panel-exit-sequence = [
05 05 01 28
05 78 01 10
];

vsync-len = <1> ;
vback-porch = <15> ;

hsync-active = <0> ;
vsync-active = <0> ;

};
};
};
};
};
When I am starting the board then I get these errors:

Could it be, that this single error:
[ 3.001247] dw-mipi-dsi ff960000.dsi: device mode is unsupported
[ 3.007974] panel-simple-dsi: probe of ff960000.dsi.0 failed with error -22
Is the source of all the problems?
Cause after that error it looks like that it begins to repeat the messages... Could somebody give me some hints or feedback about what could be wrong here?
Thank you.
