[PATCH v2 1/3] dt-bindings: usb: gpio-sbu-mux: Add an entry for CBDTU02043

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Add a compatible entry for the NXP CBDTU02043 GPIO-based mux hardware
used for connecting, disconnecting and switching orientation of
the SBU lines in USB Type-C applications.

[PATCH v2 2/3] arm64: dts: imx8qxp-mek: Fix gpio-sbu-mux compatible

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Per gpio-sbu-mux.yaml, the compatible entry is incomplete.

The imx8qxp-mek board uses a CBDTU02043, so complete the gpio-sbu-mux
compatible accordingly.

This fixes the following schema warning:

imx8qxp-mek.dtb: gpio-sbu-mux: compatible:0: 'gpio-sbu-mux' is not one of ['onnn,fsusb43l10x', 'pericom,pi3usb102']

[PATCH v2 3/3] arm64: dts: imx8qxp-mek: Pass gpio-sbu-mux mode-switch

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Per gpio-sbu-mux.yaml, the 'mode-switch' property is mandatory.

Pass it to fix the following schema warning:

mode-switch:
    description: Flag the port as possible handle of altmode switching
    type: boolean

I don't think there is altmode enabled on iMX8QXP MEK board, there is
only an orientation switch.

Okay, so I will send a change that removes mode-switch from the
required properties list then.

Thanks
