Subject: [PATCH RFC 4/7] dt-bindings: pwm: rcar: Add specific gpios property to output duty zero
Date: Mon, 8 Jul 2019 18:07:45 +0900 [thread overview]
Message-ID: <1562576868-8124-5-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <1562576868-8124-1-git-send-email-yoshihiro.shimoda.uh@renesas.com>
The R-Car SoCs PWM Timer cannot output duty zero. So, this patch
adds a specific gpio property to output it.
