[PATCH 0/2] Fix kernel splats on boot with armada-37xx irqchip driver

[Vladimir Oltean]

Due to these splats on boot, lockdep disables itself on Armada 37xx and
we fail to see further useful information about real deadlocks.

For those in doubt, the approach to use raw spinlocks for irqchip
drivers has been previously discussed here and doesn't seem too
controversial.

Tested on the Turris MOX board.

Vladimir Oltean (2):
  pinctrl: armada-37xx: make irq_lock a raw spinlock to avoid invalid
    wait context
  pinctrl: armada-37xx: use raw spinlocks for regmap to avoid invalid
    wait context
