Merge tag 'samsung-pinctrl-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into devel
Samsung pinctrl drivers changes for v4.19
1. Add handling of external wakeup interrupts mask inside the pin
controller driver.
Existing solution is spread between the driver and machine code. The
machine code writes the mask but its value is taken from pin
controller driver.
This moves everything into pin controller driver allowing later to
remove the cross-subsystem interaction. Also this is a necessary
step for implementing later Suspend to RAM on ARMv8 Exynos5433.
2. Bring necessary suspend/resume callbacks for Exynos542x and
Exynos5260.
3. Document hidden requirement about one external wakeup interrupts
device node.
4. Minor documentation cleanups.
