[PATCH v5 13/17] ASoC: pxa: poodle: make use of new locomo GPIO interface

From: Dmitry Eremin-Solenikov <hidden>
Date: 2015-06-08 20:56:44
Subsystem: pxa2xx/pxa3xx support, sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Daniel Mack, Haojian Zhuang, Robert Jarzmik, Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds

Since LoCoMo driver has been converted to provide proper gpiolib
interface, make poodle ASoC platform driver use gpiolib API.
