Subject: [PATCH 4/4] arm64: dts: ti: k3-am642-evm: Add ecap0 node
Date: Mon, 19 Jul 2021 14:24:02 +0530	[thread overview]
Message-ID: <20210719085402.28569-5-lokeshvutla@ti.com> (raw)
In-Reply-To: <20210719085402.28569-1-lokeshvutla@ti.com>

ecap0 can be configured to use pad ECAP0_IN_APWM_OUT (D18) which has a
signal connected to Pin 1 of J12 on EVM. Add support for adding this
pinmux so that pwm can be observed on pin 1 of Header J12
