Subject: [PATCH v8 5/7] arm64: dts: ti: k3-am65-main: Add PVU nodes
Date: Tue, 22 Apr 2025 14:14:04 +0800 [thread overview]
Message-ID: <20250422061406.112539-6-huaqian.li@siemens.com> (raw)
In-Reply-To: <20250422061406.112539-1-huaqian.li@siemens.com>
From: Jan Kiszka <jan.kiszka@siemens.com>
Add nodes for the two PVUs of the AM65. Keep them disabled, though,
because the board has to additionally define DMA pools and the devices
to be isolated.
