Subject: [PATCH] dt-bindings: usb: ehci: Increase the number of PHYs
Date: Wed, 15 Jun 2022 15:53:09 +0200	[thread overview]
Message-ID: <c5d19e2f9714f43effd90208798fc1936098078f.1655301043.git.geert+renesas@glider.be> (raw)

"make dtbs_check":

    arch/arm/boot/dts/r8a77470-iwg23s-sbc.dtb: usb@ee080100: phys: [[17, 0], [31]] is too long
	    From schema: Documentation/devicetree/bindings/usb/generic-ehci.yaml
    arch/arm/boot/dts/r8a77470-iwg23s-sbc.dtb: usb@ee0c0100: phys: [[17, 1], [33], [21, 0]] is too long
	    From schema: Documentation/devicetree/bindings/usb/generic-ehci.yaml

Some USB EHCI controllers (e.g. on the Renesas RZ/G1C SoC) have multiple
PHYs.  Increase the maximum number of PHYs to 3, which is sufficient for
now.

Fixes: 0499220d6dadafa5 ("dt-bindings: Add missing array size constraints")
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

usb_phy_roothub_alloc() just loops over all PHYs found.
