[PATCH v2 0/3] pinctrl: starfive: jh7110: support force inputs

[Icenowy Zheng]

The input signals inside the JH7110 SoC (to be routed by the pin
controller) could be routed to GPIOs and internal fixed low/high levels.
As the total GPIO count of JH7110 is not very high, it's sometime
feasible to omit some hardwiring outside the SoC and do them in the pin
controller. One such example is the USB overcurrent_n signal, which
defaults to low at SoC reset, needs to be high for the USB controller to
correctly work (the _n means low indicates overcurrent situation) and
gets omitted on the Pine64 Star64 board.

Add the support for hardwiring GPI signals inside the JH7110 pin
controllers, via two virtual "pins" which mean fixed low/high.

Changes in v2:
- Use virtual pins instead of special properties.
- No longer RFC.

Icenowy Zheng (3):
  dt-bindings: pinctrl: starfive,jh7110: add PAD_INTERNAL_* virtual pins
  pinctrl: starfive: jh7110: add support for PAD_INTERNAL_* for GPI
  riscv: dts: starfive: jh7110-pine64-star64: force no USB overcurrent
