Subject: [PATCH v3 7/7] dt-bindings: tda998x: add the calibration gpio
Date: Mon, 09 Apr 2018 13:16:43 +0100 [thread overview]
Message-ID: <E1f5Vj1-0002Lx-Hz@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20180409121529.GA31403@n2100.armlinux.org.uk>
Add the optional calibration gpio for integrated TDA9950 CEC support.
This GPIO corresponds with the interrupt from the TDA998x, as the
calibration requires driving the interrupt pin low.
Reviewed-by: Rob Herring <robh@kernel.org>
