From ba52762fb1430b2a2ea8127c1a292c15f13b8dac Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 29 Nov 2017 10:27:12 +0000 Subject: dt-bindings: tda998x: add the calibration gpio 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.
