Subject: [PATCH] phy: usb: Restructure in preparation for adding 7216 USB
|
|
support
|
|
|
|
The driver is being restructured in preparation for adding support
|
|
for the new Synopsys USB conroller on the 7216. Since all the bugs
|
|
and work-arounds in previous STB chips are supposed to be fixed,
|
|
most of the code in phy-brcm-usb-init.c is not needed. Instead of
|
|
adding more complexity to the already complicated phy-brcm-usb-init.c
|
|
module, the driver will be restructured to use a vector table to
|
|
dispatch into different C modules for the different controllers.
|
|
|
|
There was also some general cleanup done including some ipp setup
|
|
code that was incorrect.
