Need help locating octeon_usb driver

Need help locating octeon_usb driver

[-- Attachment #1.1: Type: text/plain, Size: 416 bytes --]

Hello all,
I made a clean up change to the octeon-usb driver file. I tried to correct 
a checkpatch warning of exceed 80 column. However, I am not able to locate 
this driver in the device driver list during "make menuconfig". 

I have verified the driver dependencies. I am unable to understand the 
CAVIUM_OCTEON_SOC dependency. Its set to unknown. Is this something 
referred to as BROKEN???

Thank you,
Deepak.

I worked on the octeon driver during the last outreachy application 
period, and managed to break some things.

Please cross-compile this driver with the cavium_octeon_defconfig config 
file in arch/mips/configs/ to ensure that you don't do the same.

As far as I can tell though, this driver has been removed from the latest 
staging tree.

No, you need to set that hardware configuration option in order to be
able to build this.  And to do that, you have to build for the MIPS
platform, which is quite difficult usually.

Sorry about this, this driver is tough to build, and is a pain, I would
stay away from it for now until you get more experience.

thanks,

It was removed, but it's now back as people were relying on it :(

Thank you Wambui and Greg. I will pick another driver clean up else for 
now. It was a good learning though :)
