e0958405bc blackfin: extgpio: switch to gpiochip_add_data()
We're planning to remove the gpiochip_add() function to swith
to gpiochip_add_data() with NULL for data argument.

288e6eaa06 gpio: Include linux/gpio.h instead of asm/gpio.h
Most arches have an asm/gpio.h that merely includes linux/gpio.h.  The
others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected,
linux/gpio.h includes asm/gpio.h.

Therefore, code should include linux/gpio.h instead of including asm/gpio.h
directly.

Remove includes of asm/gpio.h, adding an include of linux/gpio.h when
necessary.

This is a follow-on to 7563bbf89d ("gpiolib/arches: Centralise
bolierplate asm/gpio.h").

9466a0510a Blackfin: bf538: pull gpio/port logic out of core hibernate paths
Re-architect how we save/restore the gpio/port logic that only pertains
to bf538/bf539 parts by pulling it out of the core code paths and pushing
it out to bf538-specific locations.

621dd24743 Blackfin: bf538: add support for extended GPIO banks
The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as
the other ports on the part and the same way as all other Blackfin parts.
The MMRs are programmed slightly different and they cannot be used to
generate interrupts or wakeup a sleeping system.  Since these guys don't
fit into the existing code, create a simple gpiolib driver for them.
