Subject: [PATCH] arm64: dts: ti: k3-am625-sk: Add ECAP APWM nodes
Date: Tue, 19 Apr 2022 11:59:02 +0530 [thread overview]
Message-ID: <20220419062902.196526-1-vigneshr@ti.com> (raw)
AM62 has 3 ECAP instances with 1 APWM each. Add DT nodes for the same.
Keep them disabled in am625-sk dts as these pins can be repurposed in
user exp connector.
