From ba07cc0cbb3d486366e4ae3b79e69f972d8c2c5d Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Wed, 17 Feb 2021 23:37:54 +0100 Subject: [PATCH] lantiq: fritz7320: enable USB power supply The USB ports if a FRIZZ!Box 7320 do not supply power to connected devices. Add the GPIOs enabling USB power as regulator, to enable USB power supply as soon as the USB driver is loaded.
