[i.MX8MP][Android 11.0.0_2.2.0] MIPI DSI Panel [auo,g101uan02] porting fail

[TarkerHu]

Hi,
I'was porting MIPI DSI Panel [auo,g101uan02] to [i.MX8MPLUS][Android 11.0.0_2.2.0]

I met errors:
[ 3.182138] imx_sec_dsim_drv 32e60000.mipi_dsi: Failed to attach bridge: 32e60000.mipi_dsi
[ 3.191186] imx_sec_dsim_drv 32e60000.mipi_dsi: failed to bind sec dsim bridge: -517

My device tree:
&mipi_dsi {
status = "okay";

panel@0 {
compatible = "auo,g101uan02";
reg = <0>;
status = "okay";
};
};

Could you give me suggestions to solve this problem?
Does this Panel [auo,g101uan02] need bridge?
Which Android CONFIGS must be enabled? or must be disabled?

Hi Tarker

for new mipi-dsi panel one can use rm67191 driver, for custom panel modify timings in

struct drm_display_mode default_mode and initialization code in struct cmd_set_entry mcs_rm67191[] :

Hi Igor,

Thank you for your suggestions. I'll try it.

By the way, for a new LVDS-LCD, could you also give me suggestions and tell me starting point?

Best,

Tarker
