Subject: [PATCH v2 7/7] dt-bindings: tda998x: add the calibration gpio
Date: Wed, 06 Dec 2017 12:35:54 +0000 [thread overview]
Message-ID: <E1eMYva-0004WA-Hf@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20171206123452.GA13127-l+eeeJia6m9URfEZ8mYm6t73F7V6hmMc@public.gmane.org>
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.
Signed-off-by: Russell King <rmk+kernel-I+IVW8TIWO2tmTQ+vhA3Yw@public.gmane.org>
