This is an updated version of [1] rebased on top of pinctrl/for-next. The only change is in patch 1 to remove locking in the new rockchip_set_schmitt() function.
The aim of the series is to make the Rockchip pinctrl irq_chip implementation safe for use with RT_FULL which requires that raw spinlocks are used to avoid sleeping in hardirq context.
