[PATCH v2 0/5] rockchip: Port IO-domain driver for RK3568 from linux

[Jonas Karlman]

This series port the IO-domain driver for RK3568 from linux. It is
necessary for the IO-domain setting of the SoC to match the voltage
supplied by the regulators.

The driver auto probe after bind and configures IO-domain based on the
voltage reported by the regulators. This fixes issues observed while
working on the GMAC driver for RK3568 devices. The IO-domain setting
default to 3v3, however some vccio domains may be supplied by 1v8.

This series also add a minimal generic RK356x board that only enable
eMMC and SD-card node and keep the IO-domain driver disabled. The
generic board can be used to boot from eMMC/SD-card on boards that
follow reference board design.

Changes in v2:
- Include patch to return correct voltage for switchout converters
- Simplify code that return correct voltage for buck converters
- Add a minimal generic RK356x board with IO-domain driver disabled.
- Collect r-b tags

Patch 1 adds protection so that regulator autoset only happens one time.
Patch 2-3 fixes rk8xx buck/switchout regulator driver to report correct
voltage.
Patch 4 adds the IO-domain driver.
Patch 5 adds the minimal generic RK3566/RK3568 board.
