| Subject: ARM64: dts: meson-gxl-s905x-libretech-cc: enable the USB controller |
| |
| From: Martin Blumenstingl <martin.blumenstingl@googlemail.com> |
| |
| [ Upstream commit b83687f359d9b4128073f06ab7a06489eb04aa7c ] |
| |
| The LibreTech CC ("Le Potato") board provides four USB connectors. |
| These are provided by a hub which is connected to the SoC's USB |
| controller. |
| Enable the SoC's USB controller to make the USB ports usable. Also turn |
| on the HDMI_5V regulator when powering on the PHY because (even though |
| it's not shown in the schematics) HDMI_5V also supplies the USB VBUS. |
