Subject: [PATCH 0/4] Fix Samsung pinctrl driver static allocation of GPIO
 base warning

The object of this work is fixing the following warning, which appears
on all targets using that driver:

gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.

This needs a small refactor to how we interact with the pinctrl
subsystem. Finally, we remove some bookkeeping that has only been
necessary to allocate GPIO bases correctly.

Mateusz Majewski (4):
  pinctrl: samsung: defer pinctrl_enable
  pinctrl: samsung: use add_pin_ranges method to add pinctrl ranges
  pinctrl: samsung: choose GPIO numberspace base dynamically
  pinctrl: samsung: do not offset pinctrl numberspaces
