Subject: [PATCH v6 5/5] arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub
Date: Fri,  5 Mar 2021 11:38:53 -0800	[thread overview]
Message-ID: <20210305113832.v6.5.Ie0d2c1214b767bb5551dd4cad38398bd40e4466f@changeid> (raw)
In-Reply-To: <20210305193853.2040456-1-mka@chromium.org>

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@chromium.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
