usb clock not found on imx27 when using dt

[Philippe Reynes]

Hi all,

I try to add the support of usb on my armadeus apf27,
but there is a problem when try to reclaim the clock.
imx_usb mxc-ehci.0: Failed to get clock, err=-2

To avoid adding too many attachment to this mail,
I've put all the information on a website. You can
found them here:  http://ryu.zarb.org/~trem/armadeus/


The initial issue is in the directory : 20121110

boot-3.7-rc4.log : boot log with the issue
linux-3.7-rc4.config : the configuration file for the kernel
investifation.txt : the description of my investigation.


I've tried to fix the clock issue, but another issue occurs.
The information about this "fix" is in : 20121111
boot-3.7-rc4.log : boot log with the new issue
issue.txt : the description of the change done on the kernel

I've got severals questions :
- does my dts correct with usb change ?
- does someone has already tested usb on imx27 with dt ?

Regards,
Philippe
