[PATCH v1 0/5] TH1520 SoC: Add AON firmware & power-domain support

[Michal Wilczynski]

This patch series introduces and documents power management (PM) support and
the AON firmware driver for the T-Head TH1520 SoC, as used on the LicheePi 4A
board. While part of a larger effort to enable the Imagination BXM-4-64 GPU
upstream, these patches can merge independently.
