| Series | usb: misc: adopt onboard hub support on stm32mp1 boards | expand |
Allow properties and usb-device child nodes as defined in usb-hcd.yaml, by
using unevaluatedProperties: false. By the way, remove the "companion"
property as it's redundant with usb-hcd.yaml.
As example, this allows an onboard hub, to be described in generic-ehci
controller node:
usb {
compatible = "generic-ehci";
#address-cells = <1>;
#size-cells = <0>;
/* onboard HUB */
hub@1 {
compatible = "usb424,2514";
reg = <1>;
vdd-supply = <&v3v3>;
};
};
Without this, dtbs_check complains on '#address-cells', '#size-cells',
'hub@1' do not match any of the regexes: 'pinctrl-[0-9]+'
Add support for USB2514B HUB found on stm32mp1 boards: - Extend the ehci-generic dt-binding to fully use the usb-hcd.yaml, and so the usb-device.yaml. - Add usb-device compatible ("usbVID,PID") for the USB2514B USB2.0 HUB to the onboard_usb_hub driver. - Add relevant device tree node to stm32mp15 DK boards. - Enable the onboard_usb_hub driver on multi_v7 platforms.
