Subject: [PATCH v4 0/4] pinctrl: rockchip: PREEMPT_RT_FULL fixes

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.

v4 is v3 rebased onto pinctrl/devel as of b9c6dcab265e ("pinctrl: rockchip:
rename RK1108 to RV1108").

John Keeping (4):
  pinctrl: rockchip: remove unnecessary locking
  pinctrl: rockchip: convert to raw spinlock
  pinctrl: rockchip: split out verification of mux settings
  pinctrl: rockchip: avoid hardirq-unsafe functions in irq_chip
