[PATCH v2 0/4] pinctrl: rockchip: PREEMPT_RT_FULL fixes

Show all headers | View raw

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