Subject: [PATCH v1 0/8] Add T-Head TH15020 SoC pin control

This adds a pin control driver 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.

It can be easily tested using my th1520 branch at

  https://github.com/esmil/linux.git

..which also adds the MMC, PWM, ethernet and USB drivers that have
been posted but are not upstream yet.

Jisheng: I've added this driver to the generic TH1520 entry in
MAINTAINERS like you did with your USB driver. Let me know if that's not
ok and I'll create a separate entry for this driver with me as
maintainer.

Drew: The last patch is purely based on reading the schematics. It'd be
great if you could give it a spin on real hardware.

/Emil
