Subject: [PATCH 011/171] arm64: dts: apple: Mark ATC USB AON domains as
|
|
always-on
|
|
|
|
Shutting these down breaks dwc3 init done by the firmware. We probably
|
|
never want to do this anyway. It might be possible remove this once
|
|
a PHY driver is in place to do the init properly, but it may not be
|
|
worth it.
