X-Git-Tag: v6.19-rc1~100^2~20^2~117
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fec2d8fcdedaeeb00113186c091ccd54ee4dfa00;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: freescale: imx93-phyboard-nash: Add USB vbus regulators

Add USB vbus regulators to silence the following kernel warnings:

  usb_phy_generic usbphynop1: dummy supplies not allowed for exclusive requests (id=vbus)
  usb_phy_generic usbphynop2: dummy supplies not allowed for exclusive requests (id=vbus)

Because generic USB PHY driver requires exclusive vbus regulators since
commit 75fd6485ccce ("usb: phy: generic: Get the vbus supply").
