Subject: [PATCH v2 1/2] arm64: dts: ti: k3-am62-lp-sk: Add system-power-controller
Date: Tue, 24 Mar 2026 15:44:18 +0530 [thread overview]
Message-ID: <20260324101419.95616-2-a-kaur@ti.com> (raw)
In-Reply-To: <20260324101419.95616-1-a-kaur@ti.com>
On AM62-LP-SK, the TPS65219 PMIC is the system power controller
responsible for handling system poweroff. Add the "system-power-controller"
property to the PMIC node to explicitly designate it as such.
Among all in-tree device trees using the TPS65219 PMIC (verified via
compatible string), AM62-LP-SK was the only one missing this property.
This patch corrects that omission.
This property will be used by the PMIC driver to conditionally register
the poweroff handler, ensuring only the designated power controller
registers for system poweroff operations.
