2016-01-05pinctrl: cherryview: use gpiochip data pointerLinus Walleij
This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of().

2015-12-26pinctrl: sunxi: Be sure to clamp return valueLinus Walleij
As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern.

2015-12-22pinctrl: mediatek: convert to arch_initcallDaniel Kurtz
Move pinctrl initialization earlier in boot so that real devices can find their pctldev without probe deferring. Note: We don't change mt6397 probe order in this patch, since MT6397 is mfd PMIC, which depends on pwrap on main AP to work. Since pmic-wrap itself is module_platform_driver, we keep it as module_init. A later patch will convert both pmic-wrap, and all functions of the MT6397 mfd to arch_initcall.
