Subject: [PATCH RFC v3 1/6] arm: dts: marvell: armada-388-clearfog: enable
third usb on m.2/mpcie
Armada 388 Clearfog Pro has a USB-2.0 capable minipcie connector "CON2".
Clearfog Base has an M.2 connector combining USB-2.0 and USB-3.0 plus
various pins controlled by the host:
- FULL_CARD_POWER_OFF#: When low, M.2 LTE modules are switched off.
Many modules include pull-down, thus it must be driven high actively.
- RESET#: Puts modules into reset when low. Modules are expected to
include pull-up.
- GNSS_DISABLE#
- W_DISABLE#
Enable the usb controller node for the first combined usb-2.0/3.0
controller, for both clearfog base and pro.
To Clearfog base add gpio hogs for power-off and reset to ensure
modules are operational by default.
