Add generic access ops for controllers with a ulpi viewport register
(e.g. Chipidea/ARC based controllers).
I can see mxc, msm and langwell are using the same bits
(or at least some of them).
They all use the Chipidea/ARC usb controllers.
This means, that it is not generic, but Chipidea/ARC usb controller specific.
And it is common to some/many platforms.
Yes
Can it be utilized on platforms that have another kind of ulpi access register?
I don't think so
Is there some kind of specification for this ulpi viewport register?
You can find the Chipidea/ARC datasheet in IMX35 datasheet ( got 0x0170 ULPI VIEWPORT) or a newer version (extra fields in some registers but miss 0x168-0x170) in
http://www.nxp.com/documents/user_manual/UM10314.pdf
I don't have the IMX35 datasheet which describes the USB OTG registers.
The one that can be downloaded from Freescale website, only describes
hardware and no ULPI viewport is mentioned there.
From freescale.com I manage to download IMX35RM.pdf witch describe it
(p2075).
