   4 Subject: [PATCH 04/90] ARM: dts: sun6i: mixtile-loftq: Add USB1 VBUS regulator
   5
   6 This board is configured with CONFIG_USB1_VBUS_PIN="PH24", but no
   7 regulator exists in its device tree. Add the regulator, so USB will
   8 continue to work when the PHY driver switches to using the regulator
   9 uclass instead of a GPIO.
  10
  11 Update the device tree here because it does not exist in Linux.
