-Subject: [PATCH] ehci-platform: Add support for controllers with multiple
- reset lines
-
-At least the EHCI/OHCI found on the Allwinnner H3 SoC needs multiple
-reset lines, the controller will not initialize while the reset for
-its companion is still asserted, which means we need to de-assert
-2 resets for the controller to work.
