H A D | rk3399-puma.dtsi | 884ad05d Wed Nov 22 10:15:19 CST 2017 Philipp Tomsich <philipp.tomsich@theobroma-systems.com> rockchip: dts: rk3399-puma: add a 'tsd, usb-port-power' stringlist for USB1 USB1 is connected to the on-module USB 3.0 hub and power to the hub (actually it's a reset signal, modeled as a fixed regulator, that will be released) should be enabled only during the first probing of the device to avoid the hub from entering its low-power mode (where it tries to attach on a fixed interval, but we always miss the timeslot when U-Boot has the controller listening). This adds a 'tsd,usb-port-power' stringlist to enable the infrastructure in the board-specific usb_hub_reset_devices to find and control the fixed regulator associated with control of the USB hub.
