From 4da4883613f62d4d60ada443d09ac36644f27d8a Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Wed, 24 Dec 2025 12:45:21 +0200 Subject: [PATCH] arm64: dts: qcom: hamoa: Add the APSS watchdog The watchdog support in EL1 is SBSA compliant, handled by Gunyah hypervisor, but in EL2. the watchdog is an instance of the APSS WDT HW block, same as older platforms. So describe the APSS WDT node and mark it as reserved, as it will only be enabled in EL2 overlay.
