Dear sir,

Thanks for your response.

I still have two queries,please help me.

1.I can see such as "DRM bridge","panel bridge" "MIPI bridge" etc. in the code,so,what's the "bridge" means here,are they specified chipset?

2.DRM part should depend on specified chipset supporting(GPU/DPU/?)?

Thank you.

Hi keil

1. "bridge"means peripheral attachment bus and used as general term in many places

of attached Linux Manual.

2. in general yes, in particular sect.6.4.1.1 Introduction Linux Manual describes:

"..display framework which is fbdev framework on i.MX 6 and i.MX 7 and drm framework for i.MX8. ."

Dear Sir,

Thanks for your response.

I have checked the DWC MIPI DSI driver code you shared which is based on DRM display framework.

It's a pity that my code base still using fbdev model,so could you help check that driver code using fbdev model as well ?

Thanks.
