[PATCH v5 0/2] Add R8A7790/Lager board PCI USB DT support

[PATCH v5 0/2] Add R8A7790/Lager board PCI USB DT support

[Sergei Shtylyov]

Hello.

   Here's the set of 2 patches against Simon Horman's 'renesas.git' repo's
'renesas-devel-v3.16-rc2-20140623' tag. Here we add PCI USB device tree support
for the R8A7790-based Lager board. As the 'pci-rcar-gen2' driver device tree
support has been merged for 3.16, this patchset can now be merged too...

[1/2] ARM: shmobile: r8a7790: add internal PCI bridge nodes
[2/2] ARM: shmobile: lager: enable internal PCI

WBR, Sergei

Thanks for testing. Just one quick question from my side: Which USB
port did you test?

I somehow assumed that at least the majority of the USB ports on R-Car
Gen2 require a USB PHY device driver to work?

I tested usb ch1 only...

Thank you for the point.
About usb ch1, a USB PHY device driver doesn't need, I think.
But, about ch0 and ch2, I think that they should require a USB PHY device driver.

    Note that channel #2 also should work.

    Only channel #0 requires the PHY driver as the default routing for USB0 is 
to USBHS; channel #2 is routed to OHCI/EHCI by default.

Thank you for the point.
I tried to test usb ch2, and then it worked on my environment.

    In fact, channel #2 also works without the PHY driver as the default 
UGCTRL2 setting route USB2 pins to OHCI/EHCI.
