[PATCH v2 0/8] sunxi: Control USB pins and supplies via DT regulators

This series removes some old custom non-DM code from the Allwinner USB
PHY driver. So far we were relying on Kconfig specified GPIO names for
the VBUS power supplies, USB ID detect pin and the VBUS detect pin.
The first 5 patches resurrect Samuel's series from 1.5 years ago, fixing
one issue that prevented this series from being merged earlier (by using
regulator_set_enable_if_allowed()). This involves adding a new regulator
driver, for the AXP DRIVEVBUS functionality, then switching the USB PHY
over to using DM compliant regulator calls. Eventually the old, no
longer needed symbols are removed both from the Kconfig and the defconfig
files.
This also fixes a lot of A20 boards (probably even more SoCs from this
era), where USB was broken since v2025.01-rc1, due to conflicts between
"regulator-boot-on" DT regulators and the same controlling GPIO being
claimed by the current custom code.
The last three patches convert the currently Kconfig defined USB ID
detect pins (to switch between host and device support on USB-OTG ports)
and the VBUS detect pins (to detect external VBUS power supplied by the
connected host) to DT based GPIO pins. This changes the driver in the
first two patches, then removes the old symbols in the third one.
Please have a look and most importantly test USB host and device
functionality on any boards you have access to.
Cheers,
Andre
