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

The Genesys Logic GL850G is a USB 2.0 Single TT hub controller that
features 4 downstream ports, an internal 5V-to-3.3V LDO regulator (can
be bypassed) and an external reset pin.
Add a device tree binding for its USB protocol part. The internal LDO is
not covered by this and can just be modelled as a fixed regulator.

Use GPIO flags. What did you fix in the example?

It used to be here, but using it needs another include, which I don't
think it necessary here.
Maybe I should just drop this line in the example?

The header is necessary for the flags...

It's useful. The example should be rather complete, not just compatible
and reg.
Different problem - you miss maxItems for the GPIOs.

Genesys Logic GL850G is a 4-port USB 2.0 STT hub that has a reset pin to
toggle and a 3.3V core supply exported (although an integrated LDO is
available for powering it with 5V).
Add the support for this hub, for controlling the reset pin and the core
power supply.

Rongpin RP-H6C is an Allwinner H6 SoM by Rongpin, with Allwinner H6 SoC,
AXP805 PMIC, LPDDR3 memory and eMMC storage on it.
RP-H6B is their official evaluation board of RP-H6C, with an onboard
GL850G USB hub, Ampak AP6212 Wi-Fi module and some circuits about LVDS
display. It also exports the OTG USB port, the USB 3.0 port, PCIe bus
(as mPCIe slot), internal Ethernet PHY, analog audio/video and HDMI
port.
Add a DTSI file for the SoM and a DTS for the full board.

Changes in v2:
- Name all regulator nodes regulator-xxx.
- Fixed underscores in node names.

Rongpin RP-H6C is an Allwinner H6 SoM by Rongpin, with Allwinner H6 SoC,
AXP805 PMIC, LPDDR3 memory and eMMC storage on it.
RP-H6B is their official evaluation board of RP-H6C, with an onboard
GL850G USB hub, Ampak AP6212 Wi-Fi module and some circuits about LVDS
display. It also exports the OTG USB port, the USB 3.0 port, PCIe bus
(as mPCIe slot), internal Ethernet PHY, analog audio/video and HDMI
port.
Add a DTSI file for the SoM and a DTS for the full board.

Changes in v2:
- Name all regulator nodes regulator-xxx.
- Fixed underscores in node names.
