[PATCH v2 0/4] pinctrl: rockchip: PREEMPT_RT_FULL fixes
From: John Keeping
Date: Wed Mar 15 2017 - 14:09:53 EST
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.

pinctrl: rockchip: remove unnecessary locking

pinctrl: rockchip: split out verification of mux settings
pinctrl: rockchip: avoid hardirq-unsafe functions in irq_chip
