[PATCH v2 1/5] dt-bindings: reset: thead,th1520-reset: Remove non-VO-subsystem resets
Posted by Yao Zi 2 weeks, 3 days ago
Registers in control of TH1520_RESET_ID_{NPU,WDT0,WDT1} belong to AP
reset controller, not the VO one which is documented as
"thead,th1520-reset" and is the only reset controller supported for
TH1520 for now.

Let's remove the IDs, leaving them to be implemented by AP-subsystem
reset controller in the future.

Fixes: 30e7573babdc ("dt-bindings: reset: Add T-HEAD TH1520 SoC Reset Controller")
