Implementing new fb driver

Hi there, I will be implementing a framebuffer driver for an internally developed video adapter.

This adapter is able to change resolution and bit depth, has hardware mouse support and bitblt acceleration. It will be for the ARM9 architecture (AHB bus).

The question is: is there an API to implement to give access to these features? Which driver you think can be considered similar to take inspiration from?

Sorry for the stupid questions but I'd like to design a good interface before beginning to hack... :)

bye
Alessio
