[PATCH 0/4] Add reset controllers for other TH1520 subsystems

Posted by Yao Zi 1 month ago

TH1520 SoC is split into several subsystems, and each of them comes with
distinct reset controllers. We've already had the one for VO subsystem
documented as "thead,th1520-reset" and supported, and this series adds
support for others, including AO, VI, MISC, AP, DSP and VO.

Note the reset controller for AO subsystem is marked as "reserved" in
devicetree since AON firmware may make use of it and access in Linux
side may cause races.

This series is based on next-20250829, thanks for your time and review.

Yao Zi (4):
  dt-bindings: reset: thead,th1520-reset: Add controllers for more
    subsys
  reset: th1520: Prepare for supporting multiple controllers
  reset: th1520: Support reset controllers in more subsystems
  riscv: dts: thead: Add reset controllers of more subsystems for TH1520
