Subject: [PATCH v6 5/5] arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub
Add nodes for the onboard USB hub on trogdor devices. Remove the
'always-on' and 'boot-on' properties from the hub regulator, since
the regulator is now managed by the onboard_usb_hub driver.
Signed-off-by: Matthias Kaehlcke <mka@...omium.org>
---
Changes in v6:
- added 'companion-hub' entry to both USB devices
- added 'vdd-supply' also to hub@2
Changes in v5:
- patch added to the series
