Subject: [PATCH 2/3] arm64: dts: ti: k3-am62a7-sk: Enable PWM
Date: Mon, 21 Apr 2025 19:08:50 -0500	[thread overview]
Message-ID: <20250422000851.4118545-3-jm@ti.com> (raw)
In-Reply-To: <20250422000851.4118545-1-jm@ti.com>

PWM signals can be routed to the user expansion header on am62a7
SK. Enable eCAP0, eCAP1, eHRPWM1, and route the output PWM signals
to pins on J3 header.
