DRM MSM initialization problem

[Dima Antonets]

Hi all,

I need an advice for the following DRM MSM initialization problem:
drm/msm/msm_drv.c  msm_pdev_probe() fails with the following message (screenshot below)

[   54.833779] irq: no irq domain found for /soc/mdss at 1a00000 !

Actually, the of_platform_populate() calls from msm_pdev_probe()->add_display_components().

The MDSS IRQ domain is not initialized at this time because it will initialize later (drm/msm/mdp/mdp5/mdp5_mdss.c, mdss_irq_domain_init()), via call     component_master_add_with_match()  AFTER this error happen ..
Is it a some "trick" for init the IRQ domain early?

Thanks,
Dmitriy Antonets
