From 8248d5b3249c8a361c6906e73513769064854252 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Mon, 22 Mar 2021 13:54:28 -0500 Subject: [PATCH] arm64: dts: ti: k3-am64-main: Add hwspinlock node 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.
