Hi Andreas,

wont to talk about it. Except only if you have usb protocol analyser.
Beside, this warning is about slow path, which i would expect on this
configuration.

Hi,
On DRA7-evm, the VDDA_1V8_PHY supply must be always-on for proper functioning

the PHY's regulator during PHY pow
After clarification from the hardware team it was found that
this 1.8V PHY supply can't be switched OFF when SoC is Active.
Since the PHY IPs don't contain isolation logic built in the design to
allow the power rail to be switched off, there is a very high risk
of IP reliability and additional lea
