Message-ID: <1405128084-15731-1-git-send-email-bjorn.andersson@sonymobile.com>
Date: Fri, 11 Jul 2014 18:21:24 -0700
From: Bjorn Andersson <bjorn.andersson@...ymobile.com>

Subject: [PATCH] pinctrl: qcom: Make muxing of gpio function explicit
Instead of relying on pinmux->disable(), make the gpio function an
explicit function for all pins that supports it.
Signed-off-by: Bjorn Andersson <bjorn.andersson@...ymobile.com>
---
This fixes the regression that was introduced by removing the disable function
from the pinmux ops. I was exploiting the disable function to put the gpio pins
"back" into gpio state and this was apparently not the right way to do things.
