From a1c166aca3d555c6171e9027b81244d4c09099fa Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Sat, 25 Jun 2016 22:21:32 -0700 Subject: pinctrl: qcom: msm8974: Add hsic_ctl pinmux The msm8974 pinctrl variant has a couple USB HSIC "glue" registers that let us mux between the pinctrl register settings or the HSIC core settings for the HSIC pins (gpio 144 and gpio 145). Support this method of operation by adding hsic_data and hsic_strobe pins that can select between hsic_ctl and gpio functions. This allows us to toggle the hsic pin configuration over to the HSIC core at runtime.
