Subject: [PATCH v2 1/5] dt-bindings: reset: thead,th1520-reset: Remove non-VO-subsystem resets
Date: Mon, 15 Sep 2025 09:53:27 +0000 [thread overview]
Message-ID: <20250915095331.53350-2-ziyao@disroot.org> (raw)
In-Reply-To: <20250915095331.53350-1-ziyao@disroot.org>
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")
