Subject: [PATCH 4.17 44/46] ARM64: dts: meson-gxl-s905x-p212: Add phy-supply for usb0

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Neil Armstrong <narmstrong@...libre.com>

commit d511b3e4087eedbe11c7496c396432b8b7c2d7d9 upstream.

Like LibreTech-CC, the USB0 needs the 5V regulator to be enabled to power the
devices on the P212 Reference Design based boards.
