Hi,
Patches are independent, please pick up as you wish.
However all of them are needed to solve the issue, so I am sending
everything together for easier testng.
Problem
=======
When Odroid U3 (usb3503 + smsc95xx + max77686) boots from network (TFTP),
the usb3503 does not show up in "lsusb". Hard-reset is required, e.g.
by suspend to RAM. The actual TFTP boot does not have to happen. Just
"usb start" from U-Boot is sufficient.
Solution
========
Perform real hardware reset (including regulator off/on) when probing.
Tested on Odroid U3 so far. Please kindly test on X2 and other
configurations and bootloaders.
Best regards,
Krzysztof
