Hi,
Our custom board module imx8m has SN65DSI84 MIPI DSI to LVDS bridge.
We have configured the CSR register 0x18 as 6f (dual channel , format 1, 24bpp). But we are not getting any display in LVDS (blank screen with backlight glowing).
So we are trying out another way like creating two panel nodes inside mipi_dsi_bridge and using split-mode.
Below is our code from .dts file:
&mipi_dsi_bridge {
status = "okay";
split-mode;
panel@0 {
reg = <0>;
status = "okay";
compatible = "auo,g133han01";
pinctrl-0 = <&pinctrl_panel>;
backlight = <&backlight>;
bridge-i2c-bus = <&i2c4>;
bridge-info = <4>;
bridge-gpios = <&gpio5 5 GPIO_ACTIVE_HIGH>;
enable-gpios = <&gpio1 0 GPIO_ACTIVE_HIGH>;
#if useReg
power-supply = <®_gpio_lvds>;
#else
power-gpios = <&gpio5 3 GPIO_ACTIVE_HIGH>;
#endif
dsi-lanes = <4>;
panel-width-mm = <293>;
panel-height-mm = <165>;
port{
panel_in: endpoint {
remote-endpoint = <&mipi_dsi_bridge_out_odd>;
};
};
};
panel@1 {
reg = <0>;
status = "okay";
compatible = "auo,g133han01";
pinctrl-0 = <&pinctrl_panel>;
backlight = <&backlight>;
bridge-i2c-bus = <&i2c4>;
bridge-info = <4>;
bridge-gpios = <&gpio5 5 GPIO_ACTIVE_HIGH>;
enable-gpios = <&gpio1 0 GPIO_ACTIVE_HIGH>;
#if useReg
power-supply = <®_gpio_lvds>;
#else
power-gpios = <&gpio5 3 GPIO_ACTIVE_HIGH>;
#endif
dsi-lanes = <4>;
panel-width-mm = <293>;
panel-height-mm = <165>;
port{
panel_in_1: endpoint {
remote-endpoint = <&mipi_dsi_bridge_out_even>;
};
};
};
ports {
port@1 {
mipi_dsi_bridge_out_odd: endpoint {
remote-endpoint = <&panel_in>;
};
};
port@2 {
mipi_dsi_bridge_out_even: endpoint {
remote-endpoint = <&panel_in_1>;
};
};
};
};
Is our alternate way of splitting even and odd signals is correct way ?
Please provide your feedback.
Thanks,
Antony
