Subject: [PATCH 1/4] arm64: dts: ti: k3-am64-main: Add hwspinlock node
Date: Wed, 17 Mar 2021 18:09:43 -0500 [thread overview]
Message-ID: <20210317230946.23675-2-s-anna@ti.com> (raw)
In-Reply-To: <20210317230946.23675-1-s-anna@ti.com>
The AM64x SoC contains a HwSpinlock IP instance that is a minor variant
of the IP on existing TI K3 SoCs such as AM65x, J721E or J7200 SoCs.
Add the DT node for this on AM64x SoCs. The node is present within the
MAIN domain, and is added as a child node under the cbass_main node.
