I have custom board based on STM32MP157AAC3T CPU. I'm building image using yocto and board boots fine. Compared to devkit I'm using other panel .I've added driver + dts changes but I figured out that DSI drm driver is not probed. I checked dts on running system (status = "okay") also driver is compiled to kernel:
zcat /proc/config.gz | grep DRM_STM
CONFIG_DRM_STM=y
CONFIG_DRM_STM_DSI=y
I've enabled drm debug and see only other driver loaded:
[ 2.010826] [drm:drm_core_init] Initialized
[ 3.337453] [drm:stm_drm_platform_probe] stm_drm_platform_probe
[ 3.337794] [drm:stm_drm_platform_probe] drv_load
[ 3.337931] [drm:ltdc_load]
[ 3.773021] [drm:stm_drm_platform_probe] stm_drm_platform_probe
[ 3.773259] [drm:stm_drm_platform_probe] drv_load
[ 3.773415] [drm:ltdc_load]
[ 4.038804] [drm:stm_drm_platform_probe] stm_drm_platform_probe
[ 4.039058] [drm:stm_drm_platform_probe] drv_load
[ 4.039192] [drm:ltdc_load]
Any ideas what can be cause of that? Many thanks for ideas.
