Provide RESET GPIO and Power regulator for the USB PHY, the USB Host port mode and the PHY device for the controller. Also provide pin multiplexer information for USB host pins. We also relocate omap3_pmx_core pin definations so that they are close to omap3_pmx_wkup pin definations. Signed-off-by: Roger Quadros <redacted> ---
just using this thread, but a question -> I am kernel * master dec8e46 Merge tag 'arc-v3.13-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc and I see that VAUX2 which supplies USB_1V8[1] is not enabled -> I did a quick patch and it did seem to work (Usb keyboard, networking, mouse etc on my ehci ports seems to come up good) - any suggestions how we'd like to handle this?
