IMX8MM enabling MIPI panel driver for ILI9881C

Hi,

I have been trying to integrate Ilitech ILI9881C MIPI panel on my IMX8MM custom board on Android 11 environment.

I have tried to change defconfig as following:

CONFIG_REGMAP=y
CONFIG_SYSCON=y
CONFIG_DM_RESET=y
CONFIG_RESET_DISPMIX=y
#CONFIG_VIDEO_IMX_SEC_DSI=y
CONFIG_DRM_MIPI_DSI=y
CONFIG_BACKLIGHT_CLASS_DEVICE=y
CONFIG_DRM_PANEL_ILITEK_ILI9881C=y
CONFIG_DM_VIDEO=y
#CONFIG_VIDEO_LCD_RAYDIUM_RM67191=y
#CONFIG_VIDEO_ADV7535=y
CONFIG_SYS_WHITE_ON_BLACK=y
CONFIG_DRM_PANEL_ILITEK_IK9881C=y

After that, Kernel build log seems that it not includes drivers for IK9881C panel.

How can I solve this problem?

Thanks in advance.

Hi Igor,

Thank you for the answer.

But unfortunately I'm not familiar to Linux/Android. Do you mind if you tell me how to apply changes you mentioned to the source codes and modify build in detail?Some pointers to reference documents is appliciated.

Thanks in advance.
