Hi Tim:
Thanks for your tests.
Yes, it is. There are some problems when the PCIe switch is used
on the 3.1x kernel at my side too,

although the PCIe switch

is ok on FSL imx_3.0.35 kernels.
I'm debugging this issue now, and would summit the patches asap.

 From what I read, it seems Sean's series does not support PCIe switch.
At least, he hasn't got any device to test it.  And there is some
problem with PCIe switch running the latest kernel, which might not be
related to the controller driver.

I suggest we ask Bjorn to merge the v7 I sent yesterday, so that people
can have a same base to work on, and add PCIe switch support with
incremental patches.   Does that sound good to you, Tim?

Hi Shawn Guo,

I agree with your suggestion. :-)
The PCIe switch support patches can be added later, after the v7 patch for
i.MX6 PCIe controller driver is merged.

Also, if the PCIe switch support patches modify the synopsys designware PCIe
driver (pcie-designware.c), it should be confirmed by other related people.

Correct.  My series doesn't support PCIe switches mostly because I don't 
have one to test with.  It would be interesting to see if PCIe switches 
work with other Designware drivers.
