[PATCH 0/8] pinctrl: Add T-Head TH1520 SoC pin controllers

[Drew Fustini]

This adds a pin control driver created by Emil for the T-Head TH1520
RISC-V SoC used on the Lichee Pi 4A and BeagleV Ahead boards and
updates the device trees to make use of it.

Emil's series from January used separate compatibles for each pin
controller instance. Rob did not think this was appropriate because the
programming model is the same for each instance.

This series takes a different approach. There is now only a single
compatible for all pin controller instances. The pinctrl driver checks
the unit address to identity which pin controller instance is being
probed.
