Hi, I'm working on an USB gadget driver and currently I've got some questions and, as I am a newbie on this, I hope some of you can help. The hardware platform I am working on is an ARM 926EJ-S core SOC and the USB device controller is one of the IPs in the SOC core. I've read quite a lot on the Linux gadget driver architecture and I believe I've got the basic idea of it.
The development platform is running Linux 2.4.21-rmk2 and as far as I understand this version (not till 2.4.23) doesn't support USB Gadget driver. Therefore, in order to make my kernel to support it, should I patch the 2.4.31 Gadget code against my kernel? Or could I just copy whatever under drivers/usb/gadget/ from kernels (from 2.4.23 to 2.4.31) that has USB Gadget support to my current 2.4.21.rmk2 kernel and edit the Config.in and Makefile myself? And so I can start working on it. As I know that most of the development is based on 2.6 kernels and the driver model infrastructure is different from 2.4. So what's the 2.4 backport actually involved? or even from 2.4.31 to my kernel 2.4.21? There are two example codes of PCI-based USB device controller card (net2260 and goku) I found under the /usb/gadget folder (from kernel 2.4.31). Since the UDC I am working on is not PCI-based so what kind of device should I create first and then bind to the gadget driver later? These are the initial questions for now and I really need some help on this. I hope someone can enlighten me and point me to the right direction thanks.
