From d8e316376ccbe3fe365a137d8a667a33eaff1883 Mon Sep 17 00:00:00 2001 From: Manisha Agrawal Date: Tue, 3 Nov 2015 15:22:50 -0600 Subject: [PATCH] drm/omap: tpd12s015: CT_CP_HPD as optional gpio tpd12s015 HW has LS_OE, CT_CP_HPD and HPD gpios. Out of these gpios, driver only handled LS_OE as optional. The CT_CP_HPD gpio should also be treated as optional gpio as it is just a power saving feature. Some boards hardwire this gpio to be always enable. In this patch, all access to CT_CP_HPD gpio is made optional.
