Subject: [PATCH 2/4] arm: dts: k3-j7200: Add Main domain ESM support
Date: Tue, 23 May 2023 13:19:49 +0530 [thread overview]
Message-ID: <20230523074951.176649-3-n-francis@ti.com> (raw)
In-Reply-To: <20230523074951.176649-1-n-francis@ti.com>
From: Gowtham Tammana <g-tammana@ti.com>
Main domain ESM support is needed to configure main domain watchdog
interrupts to generate ESM pin events. On J7200 boards ESM error pin
output is propagated to PMIC to generate reset.
