This patchset adds support for Rongpin RP-H6B, and as a dependency,
power sequence support for its onboard USB hub, GL850G.

The first 3 patches are for GL850G, adding a binding for it and adding
its support to onboard_usb_hub driver.

The last 3 patches are for RP-H6B, also 2 for adding a binding and 1 for
the real DT.

Icenowy Zheng (6):
  dt-bindings: vendor-prefixes: add Genesys Logic
  dt-bindings: usb: Add binding for Genesys Logic GL850G hub controller
  usb: misc: onboard_usb_hub: add Genesys Logic GL850G hub support
  vendor-prefixes: Add Shenzhen Rongpin Electronics Co., Ltd
  dt-bindings: arm: sunxi: add Rongpin RP-H6B board
  arm64: dts: allwinner: h6: add Rongpin RP-H6C SoM and RP-H6B board

In this case, shouldn't ALDO3 have the same voltage constraints?

Other than these two minor issues:
