Just register it in the ingenic-dw-hdmi driver. Ok, I never though about this (as the code was not from me). We apparently just followed the IPU code pattern (learning by example). It indeed looks not necessary and would also avoid the ingenic_dw_hdmi_driver_ptr dependency. But: what is ingenic_ipu_driver_ptr then good for? If we can get rid of this as well, we can drop patch 1/10 ("drm/ingenic: Fix drm_init error path if IPU was registered") completely. > > Cheers, > -Paul > BR, Nikolaus

A quick test shows that it *is* required. At least if I configure everything as modules. But like you I can't explain why. Well, just a very rough idea (may be wrong): the bridge chain is not like an i2c bus and clients are not automatically loaded/probed if linked in the device tree. Therefore the consumer (ingenic_drm_drv) must register the "clients" like IPU and HDMI. BR, Nikolaus

Ah, I see. Hadn't checked this. > I'm not sure this is still required, maybe ingenic-ipu.c can be its own module now. What I have seen is that it has its own compatible record.

IMHO the hdmi driver (module) should be loaded on demand. Not everyone wants to have it. Well, that is the problem that needs to be solved... BR and thanks, Nikolaus
