From: Abel Vesa Date: Wed, 24 Dec 2025 10:45:21 +0000 (+0200) Subject: arm64: dts: qcom: hamoa: Add the APSS watchdog X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4da4883613f62d4d60ada443d09ac36644f27d8a;p=thirdparty%2Fkernel%2Flinux.git 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.
