Subject: [PATCH v3 4/4] mmc: sdhci-imx-esdhc: convert to use pinctrl subsystem

From: Dong Aisheng <dong.aisheng@...aro.org>

This driver is shared between many platforms. Currently only imx6q has
pinctrl support, to avoid breaking other platforms that do not have pinctrl
support to run this driver, enable pinctrl dummy state for them before
they also convert to pinctrl subsystem.

Signed-off-by: Dong Aisheng <dong.aisheng@...aro.org>
---
This patch depends on:
pinctrl: add pinctrl_provide_dummies interface for platforms to use
http://www.spinics.net/lists/arm-kernel/msg171538.html

ChangeLog v2->v3:
 * patch name updated.
   v1 name is ARM: imx6q: switch to use pinctrl driver
 * using pinctrl dummy state to avoid breaking other platforms to use this
   driver.

ChangeLog v1->v2:
 * using updated binding
