[android-porting] Android porting display on omap architecture

[Liechtenstein abbey]

Hi there,
I'm trying to port Android 7 on omap4 Device architecture. In particular I don't know the steps to do to port the lcd display drivers. Could you please suggest me any documentato that explain how to do this or a summary where I can find the steps to do it?
Thank you guys for your support!

Do you already have the LCD driver source code or you have to write from
scratch?

Anyway you have to check if your LCD driver supports a Device Tree ( DT )
mechanism and all your LCD's I/Os are correctly defined in the DT.

For more details, you check the following link:
https://source.android.com/devices/

Hope that help.

Cheers
Chinda

- ​Make sure LCD drivers are enable within the kernel​
- Also run some fbdev/fbtest like utility to ensure it works fine
- From the Android perspective it should work right after
that..if hardware/qcom/display has the default implementation on
/dev/graphics/fb0
