Subject: [PATCH 2/2] ARM: dts: broadcom: model USB VBUS power with regulator-fixed
Date: Sun, 20 Sep 2026 14:13:56 -0700 [thread overview]
Message-ID: <20260920211356.186967-3-rosenp@gmail.com> (raw)
In-Reply-To: <20260920211356.186967-1-rosenp@gmail.com>
Replace the undocumented "vcc-gpio" property on the usb2/usb3
controller nodes with the standard vbus-supply/regulator-fixed model.
Boards now declare a regulator bound to the chipcommon GPIO that
bcma-hcd used to poke directly, one per power rail.
Polarity is preserved: rails that used a GPIO_ACTIVE_HIGH are marked
enable-active-high, while the Buffalo usb3 rails keep GPIO_ACTIVE_LOW
and rely on the binding's active-low default. regulator-boot-on mirrors
the rail being left enabled by CFE so the power line is never toggled
during probe.
