Subject: [PATCH 2/4] dt-bindings: pwm: tiehrpwm: Make clock and clock-names as required properties
Date: Wed, 26 May 2021 14:13:04 +0530	[thread overview]
Message-ID: <20210526084306.6534-3-lokeshvutla@ti.com> (raw)
In-Reply-To: <20210526084306.6534-1-lokeshvutla@ti.com>

Driver fails to probe when 'clock' and 'clock-names' properties are not
populated in DT. But the binding documentation says these properties are
optional. Fix this by making 'clock' and 'clock-names' properties as
required.
